From customized t-shirts to promotional items, several industries have been using dye sublimation printing for manufacturing customized products.
Dye sublimation is a cutting-edge, effective printing process. To put it simply, sublimation is the application of graphic images on specific items, including mugs, polyester fabrics, t-shirts, plaques, coasters, signs, tiles, pillowcases and many more.
Images are transferred onto specific items using sublimation ink, sublimation paper, dyes, heat and pressure. The dye converts into a gaseous state via heat and pressure.
Despite simplifying printing and producing stunning photographic results, dye sublimation process is far from perfect. Users can encounter some challenges that can adversely affect the final product.
Here are some of the most common dye sublimation mistakes you should avoid:
Lines or Streaks In Printout
A dirty or clogged print head leads to streaks or lines in prints. Printing on a regular basis is an easy way to tackle this common issue.
All types of printing inks, including sublimation dry out quickly. It is, therefore, a good idea to use a small quantity of ink through the printer head on a regular basis. In addition to this, make sure you are cleaning the printer’s head as well.
Moisture can have an adverse impact on the printing process. During dye sublimation printing, excessive heat (400 degrees) can result in moisture that can cause ink issues, such as bleeding, color shifting, etc.
Hard substrates, such as metal cannot withstand excessive moisture. You need to protect the sublimation paper from moisture. Simply store it in a dry place.
Use a de-humidifier to reduce humidity and moisture levels in your environment. Another tip is to set the sublimation paper on the printing press. However, do not press it. You just need to expose the paper to warmth for a few seconds.
Blurry, Dull Transferred Images
If the transfers are coming out blurry, make sure you are not overpressing. Too much heat or too much time during the printing process can cause overpressing.
For starters, press items with the appropriate heat, time and pressure. Check if you are using the right sublimation paper. If yes, then check if you are using the correct side of the paper.
Black Ink Not Transferred Correctly
The intensity of black ink typically depends on quality of sublimation paper, pressure, time and temperature.
If you want rich black color, make sure you are using the right transfer pressure, time and temperature. In addition, invest in a high quality sublimation paper.
Using Low Resolution Images
Last but not least, use high quality images for creating vibrant products.
