Screen-Printing for shirts
Screen-printing is a familiar print application and is used for creating images
on t-shirts and other textiles such as hats, umbrellas, tote bags, etc. Screen-printing
is also known as silkscreen. However, screen-printing is the process used to print
CD (compact discs). With this technique, a thick layer of ink is dispensed onto
a stencil. The excess amount of ink is scraped off. This scraping of the excess
ink forces the remaining ink through holes in a stencil and creates the desired
image on the CD surface. There are several factors that can affect the screen-printing image including: 1.For screen-printing the standard line for images on disc is between 85 lpi (lines
per inch) to approximately 100 lpi, this can result in a loss of image detail. 2.Because the ink that is used in screen-printing is extremely thick, it can make
fine details including lines, and small type vanish. 3.The color surface of CD is not white, but silver therefore for white backgrounds
you have to add additional color to your design. 4.For screen-printing, spot color instead of CMYK (four color printing, cyan, magenta,
yellow, black), is used. CMYK printing can be done on CDs and DVDs however the
results are not ideal. 5.It is nearly impossible to match spot color ink to CMYK colors produced on printers.
In addition, the same ink color will appear differently on different areas of the
CD. 6. Designs that gradually fade from one color to another can be difficult to reproduce
due to the process that makes colors darker. However, the benefit of screen printing is the vivid and rich colors the process
provides, producing wonderful designs on CDs and DVDs. In addition, because the
design is part of the CD and not a label that can be removed it provides a way of
distinguishing authenticity.
