129
When is it often neccesary to go on press checks?
When custom inks or tricky substrates are involved; components may be difficult to represent faithfully with proofing
Since printing companies often operate 24 hours a day, you may find yourself invited to a press check in middle of night
130
What is a press-proof?
* It is when under special add-ons such as custom inks, applied varnishes, that may represent a challenge.
* For exacting jobs such as complex promotional pieces, or annual reports, it may be neccessary to perform a small press run to determine if everything looks okay.
* It can add considerably to job cost, it may be worthwhile to ensure the finished piece meets expectations.

The coarse stock of newspaper simply won't support fine line screens.
Ink sinks into absorbent stock and spreads, dot gain.
159
When do you use DPI, LPI, PPI and TLA?
**DPI** - describe resolution for desktop printer 600-1200 dpi; resolution of imagesetter or platesetter is usually 2400 dpi or higher
**LPI** - Describe frequency of halftone dots, measured along rows of dots
**PPI** - Describes image resolution. The rule of thumb should be 1.5 to 2 times printing screen ruling, but common convention to save images at 300 ppi
**TLA** - Three letter acronym
160
Which pattern is formed by dots?
Rosette
161
Which pattern is important to avoid?
Moire
Optimal screen angles add up to form rosette pattern but it's not noticable.
Incorrect intervals between screen angles can result in distracting moire.This can also be caused by combination of screen angles and image content such as woven fabric.
162
What can you do when you have a moire pattern?
Screen angle combinations such as 30-degree, 45 degree or 75 degree can minimize patterns. The angle of each color is chosen to minimize interference with other colors when all inks are combined in printed piece.
163
Why do you never see a moire pattern with print out from your desktop?
An inkjet printer, have stochastic output device which scatter arrangement of tiny dots to create an image, very randomly
It is also called frequency modulation
164
Define Stochastic screening
An inkjet printer, have stochastic output device which scatter arrangement of tiny dots to create an image, very randomly
It is also called frequency modulation
165
What are some of the PROS and CONS of Stochastic Screening?
**PROS:** Reduced change of moire, able to use lower resolution, print images containing more than 4 ink colros wihout screen angle, retention of smaller details in image, reduced ink usage, misregration on press less obvious, smoother rendition of skin tones
**CONS:** The need for extreme cleanliness. Dust may be bigger than stochastic dot. Modifications to RIP can be expensive ($15,000+), Slightly increased RIP time, On-press dot gain is higher than conventional screening, possiblity of visible graininess in large highlighted areas. More expensive because of special handling.
166
Why would images you see on the screen print disappointingly dull?
Because of the limitations of printing-ink spectrum
The range of color in RGB spectrum is larger compared to CMYK spectrum
167
When is a spot color neccesary?
When it fall outside of the range of CMYK
For ex: fluorescents, metalilics, bright orange or navy blue
168
What is the PMS swatchbook?
* Pantone Matching System swatchbook
* Patone 4-Color Process Guide
Recipe book for print service providers
Provides ink-mixing formulas for creating over 1,000 standard colors, many of which cannot be actually rendered for specifying colors
169
Why is it better to go to a spot color compared to 4-color job?
1. Using spot color can eliminate problems caused by slight misregistration on press
2. Difficult to keep balance of four inks consistent from one part of paper to another or from one sheet to another, multipage job
3. Any variation will result in color shifts
4. Replacing process build with single ink, simplifies registration and color-consistency issues

Why does slight misregistration occur?
* Paper is subject to small amounts of stretching due to physical stress of traveling through the press
* Press conditions are awful
* Art my suffer very small shifts
* Print that artwork in shades of single color
185
How would you use trapping to solve a color issue?
* Create a rim of common color areas that don't share a common ink
* Basically, the darker color defines the edge of object being trapped to each other, and that determines which objects spread (expand), which objects choke (contract), which objects remain sharp (unchanged)
186

1. spread
2. choked
3. left sharp
