The
end result of your printing process depends on many factors: paper,
ink, process and finishes. Here are a few topics to think about
when choosing the material you will print on and your printing process.

Printing
Process
Different presses offer different results. Offset is best used for
complicated graphics and four color photography, although sheet
size is limited. Digital is cost-effective for short runs and variable
information printing. Screen printing is valuable for combined board
printing as it does not crush the flutes. Flexography results are
highly influenced by the absorbency of the material used. Letterpress
works well for simpler markings and strong color. Take a look through

vs. Digital: Pros and Cons for more detail.
Line
Screen
The higher the line screen, the more refined your graphics will
look. Choose a line screen that will meet the demands of your design.

Budget
Accurate cost estimates must take many factors into account, including
box use, quantities, inks and papers. For sophisticated retail display,
the expense of offset, photography and many ink colors is warranted.
But for a straightforward shipping container with minimal graphics,
one-color flexography will serve your needs. The important thing
to remember is that we can work with you to make sure your project
fits your needs and your budget.
Printed
Medium
Especially when labeling combined board, consider the smoothness,
brightness and opacity of your printing medium. Smoothness is a
measure of paper surface irregularities, which affects the appearance
of printing. Aside from its aesthetic importance, paper brightness
affects the legibility and contrast of printing. Opacity is the
lack of transparency that allows a sheet to conceal print on its
reverse side.
Finishes
Think about your boxes end use and if you need special finishes
for regulated items such as food or to protect sensitive electronics.
