Be sure your squeegee is the proper length for the image area. Squeegee angle and pressure must remain consistent. If you have a four color process job pending this is a good time for a tune up. Make certain your press can hold registration. Always pre-test process inks remembering they are transparent.
Inks are a variable in process printing.
Some appear gelatinous while others, like QCM's appear more like standard plastisol. Process inks are designed to be printed on white garments or printed on a white base on dyed garments. The ink, being transparent, will allow the under color of the garment to affect the color of the printed image. Using test squares of either pellon or shirt material, tight weave. Print your cyan or blue color alone.
