Process, Uses & How It Works
Have you ever tried to figure out how bright patterns can be perfectly printed on everything, including coffee cups and sports clothing, without cracking and peeling? The solution is in sublimation printing which is an innovative process that is revolutionizing the custom printing market.
The particular feature of sublimation printing is the permanent, high quality design that is incorporated into the material to remain. Compared to transfer vinyl heat or screen printing, where the design is placed on the surface of the material, sublimation printing enters the inner structure of material on a molecular level.
This end-to-end tutorial will take you through all there is about sublimation printing. You will also find out the working process, materials that can be used or compatible, strengths or weaknesses of this process, and its suitability to your printing task. At the end, you will clearly understand why sublimation printing has emerged as the choice printing technique when it comes to creation of long lasting, professional-quality custom products.
Understanding Sublimation Printing
Sublimation printing is another form of digital printing which involves use of heat and pressure to transfer dye into substrate materials. The word sublimation is derived after the scientific process that involves the change of matter whereby a solid state can change immediately into a gaseous state without passing through the intermediate phase of a liquid.
The magic happens when specially formulated sublimation inks are heated to approximately 375-400°F (190-204°C). At this temperature solid dye particles are changed into gas and enter the surface of the compatible material. Once the heat is taken out, the gas would again solidify, however, this time, it does not come off, as it is permanently fused in the fiber or coating of the material.
The prints that this process produces are exceptionally long-lasting, fade proof and do not crack, peel or wash off. The colors are vivid since they are not on the top of the fabric- now they are a part of the fabric.
How Sublimation Printing Works: Step-by-Step Process
To learn more about the work of sublimation printing, it is necessary to divide the process into its main stages. Every stage is important to get the final high quality outcome.
Step 1: Design Creation and Preparation
Sublimation printing process starts with developing your design by graphic design software. This would have to be designed as right mirror image since it is to be flipped during the transfer process. Most designers use professional Digital software such as Adobe design programs such as Illustrator software or Photoshop or specialized kiosk sublimation design software.
At this point, color management is influential. Sublimation inks act differently compared to the conventional inks, and they commonly contain more vivid colors. Other printers design color profiles and strive to print test printouts so that the end product reflects their expectations.
Step 2: Printing the Transfer Paper
As soon as your design is completed, it is printed on special transfer paper called sublimation transfer paper with a special printer known as sublimation printer, fitted with sublimation inks. These are not ordinary desktop printer inks, but sublimation inks which are specially prepared to change their state to gas at an elevated temperature.
The printer adjustments should be adapted to the sublimation printing. This comprises using the right type of paper, managing the density of ink, and color management. Those pieces of paper with printed transfers are to be handled with care to keep them free of smudging and contamination.
Step 3: Preparing the Substrate
As preparations to transfer the paper are made, the substrate (the material on which the printing is done) should also be prepared. This is done by cleaning the surface to eliminate any dusts, oils or residues that may complicate the process of transfer.
Wet fabrics (pre-press-able items) can be dehydrated and wrinkles ironed out using a heat press. In the case of hard surfaces such as mugs, phone cases etc., a good cleaning with alcohol or any other cleaning fluid with special adhesion enhancers guarantees peak adhesion.
Step 4: The Transfer Process
Proper alignment of the transfer paper is seen by ensuring that it is placed face-down on the substrate. The assembly is settled into a heat press or sublimation oven. Temperature, pressure, and time control are important, generally: 375-400F, medium-firm pressure, and 45 to 60 seconds on most applications.
In this stage, the sublimation inks change to gas and enter the substrate. Loading the transfer paper in-between the material, the pressure guarantees an absolute contact, and the heat initiates the process of sublimation.
Step 5: Cooling and Finishing
Once a transfer time has elapsed, the substrate to which it was transferred is lifted carefully off the heat press. There are those that need prompt removal of the transfer paper and others that they cool down before removal. This is based on material specific and manufacturer recommendations.
The last stage is checking of the design transferred to make sure that it is of quality and completeness. Well done sublimation prints must exhibit good use of vibrant detail and no gaps and perfection in the coverage.
Sublimation printable materials
Sublimation printing is an activity that suits on certain types of materials. Conducting research on material compatibility is necessary to get the best results and prevent some disappointments.
Polyester and Polyester Blends
The best sublimation printing material is polyester. These synthetic fibers take sublimation dyes well and create bright durable colours. Blends of polyester with minimum 50% polyester can also be used, but you will sadly see less-vibrant areas on the non-polyester areas.
Performance textiles, athletic apparel, and most contemporary sportswear have a high polyester percentage making them a great target in terms of sublimation printing. A greater amount of polyester, the brighter and longer-lasting the end print would be.
Polymer-Coated Hard Substrates
A polymer coating can make most hard materials sublimation-compatible. This special coating is to accept sublimation dyes and provide a permanent bond.
Some polymer-coated objects that are common are ceramic mugs, mouse pads, phone cases, aluminum sheets, and different promotional products. The coating material is mostly light colored and some white to provide the appropriate color replication.
Specialized Sublimation Materials
Sublimation market has grown including a wide range of specialised materials. These are metals that are ready to be sublimated, ceramics, glass, and even wood products properly coated.
Manufacturers still develop materials that are compatible with sublimation and increase the scope of custom printing jobs. Check the compatibility of a material in terms of sublimation before starting a project.
Advantages of Sublimation Printing
Sublimation printing comes with a wide range of advantages that can be appealing both to a print shop on a professional level and individual crafters.
Durability and Longevity
Among the greatest benefits of sublimation printing, great durability stands out. Dyes are not applied on top of the material, but they become a part of it, which prevents print fading, cracking and peeling. Sublimated clothes can hold up under hundreds of wash cycles with only trivial deductions.
It is this intense resistance to chipping that leads to the sublimation printing being the most suitable when the products need to endure a lot of use like sportswear, uniforms and other promo items that are to be worn frequently.
Vibrant Colors and Fine Detail
Sublimation printing results in very bright colors and this process can yield astonishing definite details. The process can reproduce full-color, photographic quality in prints free of the restrictions commonly experienced in traditional screen printing.
Sublimation printing renders color gradients, intricate patterns, and high-resolution photographs very beautifully. A lack of dimension in pushing on the ink prevents even minute detail to appear soft.
Cost-Effective for Small Runs
Compared to screen printing where you have to spend a lot of money setting up each color, sublimation printing is very minimal set up required. This is very economical with small quantities or single productions or customized goods.
Sublimation printing is digital so complexities and number of colors incur no penalty. The monochrome plain is, with respect to cost of production, equal to a colour photo.
Eco-Friendly Process
Compared to most old print styles, sublimation print is more eco-sustainable. It has low waste, water based inks used and it does not need severe chemicals or solvents.
Sublimation prints are also durable, a characteristic that ensures the products take longer to be replaced, which helps to save the environment by minimising its effects.
Limitations and Considerations
Although sublimation printing has numerous benefits, one should know its drawbacks to set adequate expectations.
Material Restrictions
The greatest restraint of sublimation print is that it only works on polyester and materials that are polymer-coated. The dyeing with natural fibers, such as 100 cotton, linen or silk, is unable to be sublimated directly. This restricts the number of existing products in the face of other forms of printing.
But polyester with a degree of cotton may be an option but the cotton fibers do not take the dye and there will be a more vintage or distressed finish effect.
Color Limitations on Dark Materials
Installation printing is effective on light-colored or white materials. The process is unable to print white color and, therefore, the material color of the base appears through. Dark materials are special processed or printed differently.
Other manufacturers provide dark colored sublimation blanks that have light color coatings; these enhance limited design possibilities and also they can change the final product appearance.
Initial Investment Requirements
Sublimation printing will initially cost a lot to start. These will include a sublimation printer, sublimation inks, sublimation transfer paper, heat press and miscellaneous supplies. High-end equipment is able to cost thousands of dollars.
Sublimation printing is however relatively cheap per unit after getting the equipment, and, therefore, it is quite economical to produce medium and high volumes.
Applications and Uses
The sublimation printing has been used in many different industries and products.
Apparel and Textiles
Sublimation printing has been adopted in apparel industry, to design customized sports and fashion products as well as promotional clothing. The process performs incredibly well on active and performance wear, swimwear, and other products whose durability and color retention is of great importance.
Sublimation printing costs include a considerable part of the custom t-shirt, hoodies, and accessories market. It is perfect to produce one off designs which have no setup cost to it making it suited to personalised apparel.
Promotional Products
Promotional product items such as mugs, mouse pads, phone cases, and keychains are mostly suited to a sublimation printing process. Sublimated products are also in demand as corporate gifts because of their professional appearance and sturdiness, as well as marketing materials.
Sublimation printing comes to give a perfect result in event merchandising and in custom promotional campaigns due to quick turn-around time and the possibility of customizing each piece independently.
Home Decor and Personalization
Sublimation printing can be seen by replicating photographic imagery in photo panels, canvas prints, and custom tiles that are found in home decor offerings. The prints are permanent and they will last years.
Another large market of sublimation printing is the personalized gifts. Products such as personalized photo mug, personalized phone covers, and commemorative products take advantage of the long-lasting, poignant nature of the product that the process creates.
Equipment and Supplies Needed
To introduce sublimation printing, particular elements and tools necessary to do it are needed.
Sublimation Printers
Specifically designed or adapted to accept sublimation inks, sublimation printers work with sublimation ink. Epson EcoTank powered printers, Sawgrass Virtuoso family, and wide printers are more popular in larger applications.
The printer should be sublimation specific because sublimation ink cannot be mixed with normal inkjet ink. A lot of consumers buy entry-level printers made by Epson and modify them especially towards sublimation printing.
Sublimation Inks
Sublimation inks are those that have special formulations to go into gas state, upon being heated. The inks can be supplied in normal CMYK colors and should be properly stored so that they are effectively exploited.
Better color reproduction and longer life prints are created by quality sublimation inks. Although there exist generic inks, professional grade ones usually give better output and consistency.
Heat Press Equipment
Sublimation printing requires a good heat press. The press then has to have a uniform temperature and pressure over the surface. The alternatives are clamshell press, swing-away press, and some special presses multipurpose products type mugs or caps.
The accuracy of temperatures plays a significant role in the success of sublimation. Digital controls of temperature are provided in professional heat presses along with uniform heating plates.
Transfer Paper and Substrates
Sublimation transfer paper is specifically made to take the sublimation inks and create them as heat is applied. Many types of paper weight and coatings have applications.
Substrates have to be sublimation-compatible, be they polyester garments, or polymer-coated hard goods. Better blanks translate to customer satisfaction and better results.
Getting Started with Sublimation Printing
