Line vs. Process Print
- Process print refers to finely screened prints and photographic type images.
- Process print artwork is supplied in vectorized CMYK format. Process prints are made up of 4 colors---C--Cyan, M--Magenta, Y--Yellow and K---Black. The CMYK colors are laid down in "dot" combinations to create the imagery. The CMYK colored dots overlap at a microscopic level to create the color gradations and variations that photographic imagery shows. In addition to these 4 process colors, we can print with an additional 4 spot colors for a total of 8 colors. The additional spot color options allows exact color matches when needed. The colors CMYK create can provide close to spot color matches but are not as exact as using purely that color. When exact colors are needed, that is when an additonal spot color is added to the job.
- "Line" or "Spot" color prints refer to coarser screens and non-photo images. Line or Spot color print is similar to a "stamping" a color at a time except poly is printed on a large print press in roll form and not bag by bag. On press, the material travels station to station and picks up a color. The color is trasferred via pressure and an inked print plate. The print plate transfers the image on to the plastic material. The printed poly material is then brought to a bag machine to be converted into bags.
- In general, line prints are less expensive in lower volumes in terms of bag costs and plate costs.
