T-shirt Press Machine Ulimate Guide

As one of the most popular and promising niche markets, many entrepreneurs venture into the custom T-shirt printing business each year. For startups and mid-sized businesses alike, T-shirt press machines are essential tools for performing heat transfer processes using dye-sublimation printing, HTV, and DTF printing technology. This makes a comprehensive guide on T-shirt heat press extremely important, especially for beginners lacking background knowledge in this area.

However, after thorough research on the internet, we found that most guides only offer limited or partial information. Therefore, we have decided to provide as much necessary information as possible in a single post. This way, beginners can avoid some of the mistakes we made and spend more time enjoying the transformative power of creation. Our aim is to show how custom printing can enhance people’s lives and create memorable experiences for individuals.

T-shirt Press Machine Size Guide

We’d like to begin the T-shirt press machine guide with a discussion on heat press platen sizes. When launching your custom T-shirt printing business, one of your initial decisions will involve selecting the appropriate printing size for your heat press. This decision is crucial because different heat press machines offer varying printing sizes and capabilities, influencing the scope of your business operations. In the market, most heat press machines fall into one of five categories based on their printing sizes: Extra Small, Small, Medium, Large, and Extra Large.

Extra Small: This size range is commonly referred to as the label press category, which typically includes platens sized at 4”x 6”, 5″x5″, 6” x 6”, and 6” x 8”. These are ideal for printing logos, labels, or intricate designs on various fabrics and small items like baby clothes, tote bags, or shirt sleeves. If you require printing on small areas of larger items, these sizes would be the most suitable heat press options to consider.

Small: This size range encompasses dimensions such as 9” x 12”, 11” x 15”, 12” x 15”, and 14”x 16”. The widely favored A4 size is also part of this category, often sought after by hobbyists. It serves as an excellent tool for applying 8.5” x 11” heat transfers, patches, and other small items onto garments. If you’re seeking a device for garment decoration but have limited working space, this compact size could be an ideal option for your business needs.

Standard: This size range is considered standard for the industry, covering dimensions such as 16” x 16” and 15” x 15”. These sizes are typically large enough to accommodate the needs of most decorators. Heat presses of these sizes often boast greater wattage, facilitating the completion of repetitive prints with ease. Additionally, they are more cost-effective than the next size up. If you’re considering starting a print shop or expanding your custom apparel business, and you need to transfer designs onto various items like t-shirts, sweatshirts, tank tops, totes, mousepads, and more, this size range may be suitable for your needs.

Standard Large: The standard large size, typically 16” x 20”, is one of the two most popular heat press sizes, alongside the 15” x 15” option. This size is renowned for its versatility, capable of effortlessly accommodating the needs of most apparel decorators. It can effectively apply 11” x 17” transfers, making it ideal for standard sizes of t-shirt designs, such as full fronts and full backs. Additionally, it’s suitable for tasks like applying names and numbers for sports teams, offering ample space for various design applications.

Extra Large: The extra-large size range encompasses heat press sizes ranging from 18” x 20” to a colossal 40” x 64”. These presses boast expansive dimensions beyond the typical requirements of most users and come with a hefty price tag. Considering their substantial size and cost, they may not be the most practical choice for standard t-shirt printing applications. If you’re contemplating investing in a heat press of this magnitude, it’s advisable to seek professional guidance to ensure it aligns with your specific business needs and objectives.

While the size chart serves as a general guide, selecting the perfect heat press machine can be a more complex decision. To make a well-informed choice, you may want to refer to our previous post titled “Heat Press Sizes Guide for T-Shirt Printing Business” which offers detailed information on size considerations.

T-shirt Design Size & Placement Guide

The next challenge facing newcomers in the T-shirt printing business is determining the size and placement of designs on T-shirts. Designs intended for full front or left chest placement, for instance, require different sizes and positions. The accuracy of your design placement significantly impacts the visual impact of your product, making it a critical factor in your business’s success. To provide guidance, we’ve created an image guide showcasing the eight most popular design placements. This guide includes recommended design dimensions and placement positions for each option.

Heat Press Settings Guide on T-shirt Printing

When it comes to T-shirt heat press, one of the most common questions revolves around heat press settings. Before delving into specifics, it’s important for us to reach an agreement on the following points:

Ultimate Heat Press Guide
Ultimate Heat Press Guide
  • Different printing techniques may have limitations regarding the types of fabric they can be used on. For instance, dye-sublimation printing is suitable only for polyester-based fabrics, while HTV works best on cotton, polyester, or cotton/poly blends, and DTF printing can be used on most fabrics available in the market.
  • Various fabrics react differently to heat, necessitating distinct heat press settings for different types of T-shirts. A recommended approach is to begin with lower temperature settings and longer pressing times, adjusting as needed based on the results of a few test prints.
  • Due to the differing techniques and principles involved, even T-shirts made of the same material may require vastly different printing settings when using different printing technologies.
  • Even when employing the same printing technology on T-shirts made of identical materials, settings may still need to be adjusted based on the supplies from various suppliers. Therefore, conducting test runs is always advisable before proceeding with bulk printing.

Given these factors, there is no one-size-fits-all solution for determining the best heat press settings for T-shirt printing. However, we’ve developed a comprehensive guide on heat press settings tailored to different printing technologies and materials. While it’s not recommended to use the settings provided in the post for your projects without testing, they do offer a helpful starting point for conducting your tests. For more detailed information, you can refer to our Ultimate Heat Press Guide.

How to choose the right T-shirt press machine for your business?

Selecting the best T-shirt press machine for your business is a significant investment decision that requires careful consideration of numerous factors. The crucial first step is to thoroughly understand your business needs before making any hasty decisions. Begin by creating a comprehensive list of factors, such as your daily printing demands, the typical sizes of designs you’ll be printing, the types of fabrics your business primarily deals with, and any advanced features that could enhance productivity. Rank these factors according to their importance, and use the finalized list to identify your ideal choice. Then, compare it with all the available options in the market to ensure you make the most informed decision possible.

If you’re unsure about which factors and features to include on this list, consider the following suggestions. We believe these factors are crucial for boosting productivity and providing significant benefits and convenience to your T-shirt custom printing business.

Heat Press Type

Before delving into other factors, you should determine which heat press type best fits your business. The market offers three main types: clamshell, swing-away, and drawer style. The most debated topic in the heat pressing community is which is better for t-shirt printing.

Clamshell heat presses are known for their space-saving feature but have limited space for garment positioning, which may increase the risk of burning. Swing-away heat presses may require more storage space, but their design provides ample room for garment placement without risk of burns. Additionally, the extra hover function enables users to efficiently perform pre-heating. Drawer style heat presses fall in between, utilizing a clamshell structure to save space while incorporating a drawer design to offer enough room for garment positioning with minimal risk. If you’re having trouble deciding, you can check out our guide on clamshell heat presses.

Printing Size

The second factor to consider might be printing size, which also involves evaluating your business needs. You can start by checking your order list to identify the most common sizes you deal with daily. If your business is growing rapidly, you should also consider the potential for future growth when choosing the size to meet your future demands, eliminating the need to purchase additional devices. Additionally, we offer extra advice on selecting the right size for your business in our heat press size guide post, where you can find additional information.

Even Heat Distribution

To achieve perfect prints, it’s essential to have precise and uniform heat distribution during heat transfer. This is often determined by how suppliers arrange their heating elements in heat press equipment. You can assess performance by testing heat distribution using a thermometer. For example, when testing a heat press from Galaxy Press, you may discover that the temperature differences across the printing surface are less than 5°C. This is because Galaxy Press employs unique technology and superior materials to minimize heat differentials, ensuring that users consistently achieve their intended designs for their projects or orders.

Precise Setting Control

To achieve the desired outcome, it’s crucial to select a t-shirt press machine with precise control over all settings. While most suppliers and their devices offer the ability to have precise temperature and time settings, many products lack the capability for precise control over pressure, which might potentially impact the final results. Thus if your budget is sufficient, you might choose one with precise settings on pressure.

Durability and Build Quality

When making decisions about equipment for your business, it’s crucial to prioritize quality over price, as the investment should take into account long-term benefits rather than just upfront costs. Opting for a sturdy and durable machine that can withstand the demands of your business’s production volume ensures reliability and consistency in output (For example, Galaxy Press provide a 10 year warranty for GS-105HS heat press heating platen). Additionally, investing in quality equipment often translates to higher performance, contributing to increased efficiency and productivity. Therefore, while initial expenses may be higher, the superior performance and longevity of a quality machine ultimately provide greater value and return on investment over time.

Ease of Use

The next step is to select a user-friendly heat press machine for t-shirt printing. A tuitive heat press machine allows operators to quickly and efficiently set up and execute printing jobs, reducing downtime and increasing productivity. It requires less time for training new employees, allowing them to become proficient in operating the equipment more quickly and effectively. What’s more, intuitive controls and clear instructions reduce the likelihood of operator errors, leading to fewer mistakes and less waste of materials and resources.

Brand Reputation and Support

Research reputable brands with positive customer reviews and reliable technical support to ensure peace of mind and assistance when needed. In the custom printing industry, after-sale service and technical support are often more crucial than quality in some cases, particularly for those purchasing equipment from overseas suppliers. Imagine if your equipment encounters a problem and your business is forced to shut down for several days; it would be disastrous for business owners. That’s why Galaxy is committed to developing a global dealer network and requires our dealers to have technicians who can provide the most prompt and considerate service and support to local users.

Best T-shirt Heat Press Machine for Business Beginners

For business starters or home business owners with limited budgets or space constraints, the ideal t-shirt press machine from the Galaxy Press product line is the GS-804 heat press. We recommend this model over the GS-805 hobby model because the GS-804 is an A3 heat press, capable of meeting the demands of printing most garments. In contrast, the GS-805 is only suitable for A4 size designs, which may limit the scale of your business.


Best T-shirt Heat Press Machine for Advanced Business Runners

For advanced business owners with high daily printing demands and a complex product line, the top recommendation would be the GS-105HS auto heat press machine. It offers the most popular printing size options of 16″*20″ or 15″*15″, and it’s the largest printing size available among our product line. For most businesses, all their garment decoration ideas can be accommodated with this machine. Apart from these features, there are some other reasons why we believe advanced users should consider this model.

Drawer Design

As mentioned earlier, one method of creating ample space for garment positioning in clamshell heat presses is by utilizing a drawer design. This approach is employed by both the GS-804 and GS-105HS models, facilitating user convenience and efficiency in completing tasks effortlessly. Galaxy Press takes this concept a step further by ensuring there is ample space beneath the lower platen. This design enhancement allows users to easily switch between printing on the front and back sides of garments, which proves immensely beneficial for projects requiring printing on both sides.

Patented Ramspin Design – Quick Switch Between Auto/Manual Open

Another feature shared by both models is the patented Ramspin design. This innovative feature enables users to switch between Auto and Manual open modes simply by flipping over the spin control.

Precise Pressure Control

In our discussion on achieving precise control over heat press settings, we highlighted that while most devices enable precise control over temperature and time, they often lack precision in pressure control. Although this may not pose a major issue after initial printing tests, a precise pressure control system could substantially enhance productivity. To ensure the best user experience, the GS-105 incorporates a pressure scale system, indicating pressure levels from 1 to 9. This feature empowers users to gauge and adjust the pressure with confidence, ensuring optimal printing results.

Patented Ramlock Design – Quick Change of Platen Size

When it comes to T-shirt printing, varying platen sizes are often necessary to accommodate different designs on different areas of the garment. For instance, a long strip design platen is ideal for printing on sleeves. Therefore, we offer a diverse selection of platen sizes for both the GS-105HS and GS-804 models. Below is a comprehensive list detailing all available sizes for our current heat press models.

This innovative feature enables swift and effortless changes between various platen sizes, enhancing efficiency and convenience for operators. With the Ramlock system in place, users can swiftly adapt their heat press to accommodate different garment sizes and printing requirements with ease. This streamlined process ensures minimal downtime and maximum productivity, allowing for smooth transitions between printing tasks.

Dressable Design

To further streamline T-shirt printing for operators, Galaxy Press employs the dressable design across all flat heat press machines. This unique feature incorporates a laser-cut base that enables users to dress garments over the lower platen without causing any stretching. It’s a straightforward process: load the shirt onto the platen and then feed the bottom of the garment through the clearance underneath the lower platen.

7 Expert Tips on T-shirt Printing with Heat Press Machine

Even without the best T-shirt heat press machine or printing machine at hand, getting the perfect printing result might still need some extra tips or at lease some tips would increase the properly of getting desired results. Following are some best practices that we think could really help with T-shirt printing beginners to generate better results.

Printing Test: While we’ve offered numerous guides on design sizes, placement, and heat press settings, it’s crucial to recognize that many factors can influence the final result. Therefore, before proceeding with bulk printing, it’s paramount to conduct several tests and calibration sessions until the ideal result is achieved.

Use Quality Equipment & Supplies: If you’re aiming for a long-term business venture, whether it’s establishing your own brand or pursuing a lifetime career, prioritizing 100% customer satisfaction for every order is paramount. While cutting costs on supplies or equipment may seem beneficial in the short term, it could potentially undermine your business reputation over time. Ultimately, jeopardizing the quality of your products or services could erode the foundation you’ve painstakingly built, undoing all the time and effort invested in your business.

Use Tools When Necessary: While printing T-shirts without tools may suffice in many cases, employing them can notably boost productivity and enhance results. For instance, a teflon sheet ensures even heat distribution, while a teflon pillow proves invaluable for printing shirts with buttons or collars. Additionally, alignment tools facilitate precise and efficient garment positioning.

Know The Limits: Understanding the limitations of each printing technique is equally essential, especially concerning different fabrics, design colors, and intricate design details. Conducting printing tests can also help in comprehending how different fabrics and suppliers interact, allowing you to determine the best combination for achieving optimal results consistently.

Pre-heating Is Important: Prior to thermal transfer, it’s crucial to pre-heat your t-shirts or other garments. The primary purpose of pre-heating is to eliminate moisture from the fibers and smooth out any wrinkles that could potentially affect the printing result.

Keep Learning: There’s no single book with all the answers, especially in the T-shirt printing industry. Every day presents an opportunity to discover something new. If you encounter questions or doubts, don’t hesitate to discuss them with colleagues, search for answers online, or consult with experts in the field.

Regular Maintenance Is Essential: Your equipment serves as your business partner or companion throughout your entrepreneurial journey. Ensure the longevity and reliability of your heat press machine by keeping it clean and well-maintained. Regularly remove any residue or debris from the platen and conduct routine checks on temperature and pressure settings. This proactive approach not only guarantees consistent printing quality but also extends the lifespan of your equipment, allowing it to continue supporting your business endeavors effectively.
