How to Distinguish the Printing Side of Sublimation Paper?

   Sublimation paper has the printing side, do you know it? Many customers told me that their printing quality is poor, and i found that many of them print on the wrong side. How to distinguish the right printing side?

   For roll sublimation paper, the manufacturers will put the printing side on the outside. After you receive the roller sublimation paper, you only need to install the paper into your printer as usual, and then start your work.


   For sheet sublimation paper, thing will be more difficult. But don’t be afraid, we have 2 tips.

   1. Fell the paper, the printing side will be more smooth than the other side.

   2. Wet your thumb and forefinger and pressing paper into one of its ends, the right side to sublimate it will be stick more firmly to the finger and this is because it is the side containing the polymer layer that makes it ideal for sublimated.

   3. Nowadays, in order to make the unti-curl sublimation paper, we will have a back coating. If you buy this kind of paper, you will find the color in both sides are different. You can ask your supplier which side is correct.

   With our tips, we can make sure that you will never print on the wrong side anymore.

Skyimage New Sublimation Paper with 3 Layers of Coating

   What determine the quality of the sublimation paper? It is the coating. The better coating usually means higher quality sublimation paper. Usually the sublimation paper only have 2 layers of coating, and now we developed a new sublimation paper with 3 layers of coating.

   1. The first coating: pre-coating
   As we all know, it is hard to guarantee the evenness of the base paper, sometimes you can see some impurities or holes on the paper. Because of that, the surface of the paper will not be smooth, and even hurt the print head when sublimation printing. The pre-coating is a process which can help us make the surface of paper become smooth.

   2. The second coating: sublimation coating
   This is the most important step, and also the essential step for making sublimation transfer paper. This layer are used to absorb the sublimation ink when inkjet printing.

   3. The final coating: back-coating
   Many paper manufactures will choose back-coating, because it can help the paper become more hard, and then become anti-curl. One of the headache problem for sublimation printers is the crimp of paper, this problem will not only affect the quality of printing, but also harmful for the print head. The back-coating can help you solve this problem effectively.

3.Drying Problems

Ink drying problem can cause unwanted results. If the ink is not dry on paper during production with a heat press, ink cannot be able to transfer to its intended target and results in bleeding of image and ghosting problem (as mentioned above) as well as color shifting.

In such a case, firstly, you should protect your transfer paper from moisture absorption. So, you should your transfer paper in dry place.  Be sure that transfer paper is stored in its original package. Thus, climate conditions will not adversely affect the paper. You should set the paper at least 24 hours before you use it, allowing the paper to adapt itself to environmental conditions. On the other hand, if there is a high level of humidity, use devices to balance the moisture in printing and storing area. Yet, bear in mind that the ideal operating conditions for sublimation are 25 C with 45% relative humidity. It will also help your print machine and ink to stabilize at optimum level.

In addition, if you prefer “fast dry” coated papers amonst those available in the market, you can avoid potential problems in this regard.

The problem of color mis-match is not simply result of a defective system, instead, it involves many components. The first and foremost, while the computer monitor displays in RGB mode, the printer prints in CMYK mode. And with sublimation, another pressing process is required to get the final color. It is a sort of like translating from one language to another. Just as there is rarely direct word-word match-up in translation, so we see the same situation for the color management. It should be noted that the color displayed in computer screen may not match the output of the printer, so spending time to match the color is probably a waste of time. It is far better to be sure that the correct color management settings are being utilized to ensure color accuracy for the final product. Many RIP software programs provide free color management tools. For more advanced color management, you can buy a RIP program which provides very precise tools for managing color and controlling production.

5.Paper Curling Problem in Flatbed Printing Press

Paper curling in the edges of fabric before pressing process is one of the biggest challenges facing the sublimation transfer printing today.  If you press the paper which traps extra moisture due to the ink immediately after the print is finished, the moisture of the paper will evaporate inconsistently and the paper will curl resulting in problems during pressing and exposure. However, if you set the paper without pressing for a while, the paper will evaporate extra moisture arising from the ink. Thus, the paper will not curl during the press and you will have any problem during pressing and exposure processes.
