Problems Found among the Screen Printing Machine Users
Some ideal techniques of using screen printing machines can change some elements of printing artwork. Screen printing is not a difficult task at all. Among the screen printing machine users, we generally found a problem with printing into white print, while color print is simple. White print ink is rough and thick, making it somewhat difficult to use. Do you know why this happens and how to solve it? Neither the white ink nor your printing work is guilty of that, and it happens to the screen printing press you use. For that, you don’t need to thin the ink. At the time of the printing process, you need to apply some ideal techniques and need to change some elements.
5 secrets below may be helpful for your screen printing process.
Garments that You Should Use in Screen Printing For white ink
While starting your screen printing machine, you should use a shining or light garment instead of a dark one, as the thick white ink becomes a smash or a roadblock for the dark garments within a few minutes. You may have done your work in the wrong way, or you may have used thin ink.
Using White or Black Ink According to Density and Pigment
Understanding the density and the pigment is most important for screen printing. According to this, you should print on a lighter color garment with black ink. Blank ink needs less pigment than white ink as the black one is simple and thinner than the white one.
Adjust the Screen-to-Screen Printing Machine
You want to set up white or black ink on your desired garment. You need to make proper mesh size (ranging from 110-156), select the appropriate thickness, and lower mesh screen and higher mesh screen, smaller holes for ink pushing. Then you need to adjust the screen to the press (1/8-1/16 inch). Using off contact tab to print properly
The off contact is the distance between the print garment and the mesh. It helps the screen mesh take the ink upward, clear it, and make a good print. You can use the white ink as off contact tab and set it on the screen through all the printing strokes. Sometimes few problems arise due to lack of proper off contact. The low-off contact can’t clear the screen well. To print a quality shirt through your t-shirt screen printing machine, you need to see the screen mesh bounce off the shirt. Your work will be rough if the ink stays in the screen mesh, solve this kind of problem, your off contact needs to be up a little bit. Taking too high of the mesh raises another issue. At the last part of the spectrum, you must push the off contact downward very hard to get a quality print.
Managing the Printing Stroke
The Printing stroke means moving the squeegee along the screen printing screen. Printing Stroke is the pull to force the ink through the screen mesh and controls the squeegee’s speed, release, pressure, and angles. A screen printer should pull the squeegee at a low angle for the print stroke through the screen mesh. A new printer should give a strong focus on pressure and must not take the squeegee against the mesh. Printers should stand on the press, put pressure down, and move the squeegee back. While printing, you must know the speed of the squeegee, and it mustn’t be too slow to release appropriately.
Besides these, you have to follow some more techniques. It would help if you used a multi-station screen printing machine instead of a single station. Ink will not be released if the ink is too hot. The print area should be 320 degrees and 45 seconds.
