Two Common Sublimation Problems & How to Fix Them

sublimation blanks

Transferring an image onto an object can be challenging. You may face common sublimation problems. They can be avoided with the right method. Let's see how:

There are Bands on the Image

When you see lines of missing ink on the printed images, you are having a banding issue. The problem of missing ink bands is not due to the sublimation blanks. It is because of clogged print head nozzles. When inks dry out on the inside of the printer head, the ink flow is restricted. This results in bands of missing ink on the printout. 

The solution is to avoid having the inks dry out by either printing regularly or at least a few times per week. When the printer has not been in use for some time, the inks will dry. You can also try running a small amount of ink through the printer heads regularly using the printer’s head cleaning function. In most printers, it is automatically done when you power up the printer. However, some pointers require manual head cleaning.

Gassing Out and/or Ghosting 

The process of sublimation requires that there is no movement or shifting of either the sublimation blanks or the transfer paper during the pressing. If the transfer paper is not properly anchored or planted onto the substrate, the result will be gassing out and/or ghosting.

Ending up with an image that is blurry with a shadowy appearance on the edges is called ghosting. Gassing out happens when you notice an ink burst outside the image area.

The solution is to find a way to make sure neither the sublimation blanks nor the transfer paper shifts or moves during pressing. Heat resistant tape can be used, but ensure not to tape across the image area. Also, it is important not to use too much tape because it will hamper the ability to quickly remove the transfer once the pressing is done. 

Whichever way you decide to get the transfer paper to stick to the blanks, it is vital that when you finally remove it. It should not slide along the substrate’s surface as it will spread the dye and lead to ghosting.

Use the above tips to ensure a seamless printing process.

This article will tell how to choose the best heat transfer papers in order to get great results upon sublimation. The main thing that can ruin your t-shirt design is improper choice of heat transfer papers. The variety of different Papers in the market makes it very easy for beginners to make mistakes while buying them!  No matter what your budget is, it is not worth buying cheap heat transfer papers. The only key to success in sublimation is to choose the right paper. The major difference between sublimation transfer paper and normal paper is that sublimation paper must be able to release ink easily for image. Otherwise, it will transfer on the final product with strong ink bleeding. 1. Know your Printer The very first thing you need to know is which type of printer you are using. There are different types of sublimation papers available in the market. Sublimation transfer papers are generally divided into 2 categories, Coated and Uncoated. Most of the popular printers use Coat...

Vinyl Cutting Machine and Its Uses

Image
Vinyl is probably the most popular medium used for making signs. The material has an adhesive backing, making it easy to use on most surfaces. Vinyl cutting is the process of creating designs or signs using a computer and then having a machine cut the design onto a vinyl sheet by use of a blade.  Vinyl Cutting Machine – What Is It? A vinyl cutting machine is a machine controlled by a computer. It is much like an ordinary printer except that it has a blade instead of ink, and it cuts the design onto a vinyl sheet.  There are electronic vinyl cutters, and there are also manual die cutters. Manual cutters work by using a hand crank. They are much less expensive than electronic cutters and do not require specialized software. Designs are created by using die cuts and embossing folders.  What Can A Vinyl Cutting Machine Do? Electronic vinyl cutters come in various sizes and shapes. By using a computer and good software, the machine can be used to start a business designing an...

Sublimation Paper: Is It Really That Good?

Image
Subliming transfer papers are made using a substrate that is generally similar to standard papers. You would not be able to tell the difference between normal printer paper and sublimation paper just by touching it or feeling it between your fingers. The substrate that it's built with and how well you treat it will have an effect on how long it lasts before beginning to discolour or decompose..  The Ink: Sublimation transfer paper ink is special because in order to be sublimated, it has to go through a chemical process using heat and pressure. During this process the pigments in the sublimation ink enter into a gaseous state, but retain their original chemical and physical properties. They are then able to bond with the paper completely. Once bonded, the pigment will not rub or peel off from the paper, unless done so intentionally. The Heat: Sublimation transfer printing requires the use of a heat press to transfer your image to the substrate of your choice. The temperatures ...
