01. Don’t print over seams, pockets or zippers:
To get the best quality print possible with screen printing, you need a flat surface between the pallet and the screen. The fronts and backs of the t-shirt should be smooth and consistent, which enables you to get a perfect print every time. However, printing over a seam, pocket or zipper, it creates inconsistency and when you print over these portions, it creates a gap in the print where the ink from the screen does not touch the shirt due to the ridge.
02. Shirt’s that don’t work well with jumbo prints:
Many customers want big prints on their t-shirts and many printers do produce jumbo prints. It is fairly easy to accomplish on a regular unisex t-shirt but not so easy on other kinds of t-shirts.
- Tank Tops: Tank tops are typically low cut at both the neckline and the sleeves. Printing jumbo prints on these garments can cause defects from printing over the seams.
- V-necks: The deep cut of the v-neck may not be able to accommodate the whole of jumbo print, so make sure you print something a little smaller.
- Girls Tees: Jumbo pallets are wider than most girl tees. To get it into the press, it has to be stretched. This may cause multiple issues such as ripped fabric, loss of form, distorted images and design being cut off from the bottom or sides of the shirt.
03. Garments that don’t show much detail:
Screen printing has advanced to a point where it can create a significant amount of detail on the t-shirt, which was not possible just a decade ago. But, you can’t expect the same level of detail on all kinds of garments such as Ribbed garments, canvas, burnout tees, pique polos etc. These items don’t create much detail because they are not smooth like standard t-shirts.
04. Avoid printing on ribbed garments:
The ribbed garment provides the best form of fit among other black shirts. They stretch to meet the size of the individual wearing them. This is good news for the consumers who wear it but makes printing a problem. When ribbed garment is put on the press, it is not stretched out and the ink goes only on top of the ribs. After when the shirt is put on, the inks pull apart, exposing the gap between the ribs that are not printed.
We can apply more pressure on the press to try to force the ink into the gaps but it will not get the level of detail, it is supposed to deliver. This is why, it is advisable that printers don’t print ribbed garments and if customers insist, you have to let them know of its flaws.
05. Issues in Printing Hoodies:
Hoodies are one of the toughest garments to print on. On the other hand, it is one of the best selling items during the winter. So, here are a few issues you should be aware of while printing hoodies:
- Double lined hoodies can only print one color ink and no underbase. As they slide around on the press one cannot accurately register multiple colors.
- Sometimes the pockets have to be glued down to print on the hoodies and therefore many customers receive their hoodies pocket with traces of glue.
- Prints on the hoodies depend on the brand of sweatshirt being printed. If it is double lined, the design is usually heat pressed. Only single lined sweatshirts work with hood prints.
- Print may look irregular around the pocket seams and zippers. It may create a gap in the print which is undesirable. Printing on the seam sometimes throws the registration off leaving traces of white poking out from under the design.
- Hoodies are made with thick fabric and soak up a lot of ink. The color of the sweatshirt may influence the color of the print. To get the highest quality of print when going over zippers or pockets, it is recommended to use a 100% cotton. Or an 80/20 blend and using all discharge colors without the underbase.
- The same design cannot be printed on hoodies as well as a t-shirt. Because it requires a different set of equipment and setting. So getting the same design on t-shirts as well as hoodies may cost extra.
06. Why tri-blend tees are different?:
Flash units on presses may burn the tri-blend material, so tri-blend shirts are not underbased. Without an under base the tri-blend t-shirts will give a vintage look. For printing tri-blends, it is always recommended to use 100% water based ink. Or a water based discharge ink to get the softest print possible. If you are not using water-based ink, your only real option is plastisol ink.
