4) ideal for metallic/fluorescent colors
What are the four advantages of PMS colors?
True or false: each color is applied to surface one at a time in a layered fashion using four different plates in printing.
expanded gamut printing
What is the method of expanding the color gamut beyond what can be replicated using conventional 4-color process printing?
What are the typical colors of expanded gamut printing?
What are the processes and procedures that occur between the procurement of original artwork and the manufacture of a printing plate?
What is the proper resolution for images?
What are means of communicating among the printer, the designer, and the product manufacturer?
Fill in the blank: the primary goal of blank is to serve as verification that the entire job is accurate, make proofreading corrections, verify color separations, to get manufacturers sign off, etc.

The bulk of paper-based package printing can be grouped into which three high-volume printing applications?
What is the most widely used printing process for folding cartons?

Offset plates have two areas which are...
plate cylinder does not contact substrate
Why is offset called offset?
These qualities describe what printing process?
- traditionally sheet-fed
- very high quality printing
- economical for short and long runs
Fill in the blank: the basic idea behind offset lithography is the principles that oil repels blank

- economical for small and large runs
These disadvantages match what printing process?
- substrate needs to be clean
- clay coating is needed
- does not print well on web plastic sheets

True or false: offset is usually ruled out for flexible packaging solutions
Which printing process uses an engraved cylinder instead of a plate?
Which printing process has thousands of tiny, etched cells on its surface with varying sizes and depth that define the ink volume to be transferred onto the substrate?

- solid colors with good coverage
- clean multi-color process work
- cost effective for long run lengths
- expensive cylinders
- high-volume packaging
- no seam lines
Which printing process has inferior type and line work quality?
Under a loupe, the halftone dots from a gravure print have what kind of look?
Which printing process is exclusively web-fed?

higher cost and greater lead time
What are the two cons of rotary die cutting?

What is a line of weakness comprised of intermittent cuts and spaces?
determines force needed to break substrate
Why is the proportion between cuts and spaces critical in a perforation?
double cut score
What are pairs of offset and parallel cuts that are approximately 50% through from opposite sides of the substrate sheet?
cut & crease score
What is an alternative to the crease score or cut score for forming a folding type line of weakness usually when scores will not be visible?
