Q

What are Pantone colours?

A
  • Used to specifically match colours in a design to ink being used to print

Q

Registration Marks

A
  • Used to align printing plates in pre-flight
  • Should be clear, dark and sharp if properly aligned
  • Checked carefully often with magnifying glasses
18
Q

Bleed Margins

A
  • Used to show size of paper and where is should be cropped

- Show design where the page ends and printer where excess paper begins

19
Q

Crop Lines

A
  • Show printer where page is supposed to be cropped after printing
20
Q

Colour bar

A
  • Used for colour calibration in pre-flight

- Ensures colours are being mixed accurately by the printer

21
Q

Densitometer

A
  • Checks grey-scale is properly mixed and dark enough for the design
  • Ensures the printer is mixing and dispensing ink properly
22
Q

What quality should images be for printing?

A
  • At least 300-600 dpi
23
Q

What file types are best for printing?

A
  • Vector file types so that resizing does not effect the print, especially for text
  • AI/EPS
  • PNG if using raster to ensure little to no compression and loss of quality
24
Q

What is a gutter and why is it important for printing?

A
  • A gutter is space between, text, images, or the edge of the page in a design
  • Ensures the page is easy to read and the design can be followed
  • Also ensures no important part of the design can be lost due to cropping
25
Q

Why are DPI/PPI important?

A
  • Dots per inch
  • Pixels per inch
  • Ensures quality of pictures are high and that it won’t appear fuzzy after printing
26
Q

74 gsm

A

Everyday home printing paper

27
Q

35-55 gsm

A

Newspaper

28
Q

105 gsm

A

Brochures

29
Q

30
Q

215 gsm

A

Business cards

31
Q

180-230 gsm

A

Magazine covers

32
Q

What is gsm? How does it effect printing?

A
  • Grammes per square meter
  • Higher gsm leads to better quality paper
  • Represents the weight of the paper
33
Q

Why is paper opacity important?

A
  • Some prints may be double sided, such as magazines
  • Printers need to ensure that the ink will not bleed through to the other side of the page
  • Both sides must be legible
34
Q

What is calendared paper?

A
  • Smooth, high quality paper
  • Primarily used for magazines
  • Process of smoothing paper to create higher quality surface for printing
35
Q

Solid Ink

Advantages?

A
  • Extremely high quality prints
  • No cartridge for ink so more environmentally friendly
  • Really nice finish due to special ink
36
Q

Solid Ink

Disadvantages?

A
  • Printer is very expensive, especially colour
  • Inks can be expensive
  • Can take longer to print and dry
37
Q

Why is colour calibration important?

A
  • Designs made on a device are typically in RGB colour space
  • To print, the design must be changed to CYMK colour space
  • Calibration done poorly can lead to inaccurate colours in print due to the change from CYMK to RGB
38
Q

What is photo reduction?

A
  • Where files/images are compressed, reducing image quality but also reducing file size
  • Done to fit purpose of file, e.g. files being emailed can be reduced in quality as the quality of the image on device can be lower than in printing
39
Q

What is duplex printing?

A
  • A printer capable of printing double sided without manual input
  • Reduces print lead time and is very useful for commercial printing
  • Home printers can still print double-sided but the paper must be flipped, increasing time + decreasing accuracy
40
Q

What is a camera ready copy?

A
  • Final state of publication before a design is printing

- All pre-flight is complete and image is ready to be sent straight to printer

41
Q

What is edge to edge printing and how is it achieved?

A
  • Printer needs to grip edge of paper to allow for it to be moved during printing process, meaning edges of page aren’t printed on
  • Instead, oversized paper is used and then cropped to size
