OUGD504//Colour for print workshop

In todays session on print production we looked at colour for print and how different colour systems can be used within printing over different formats and stocks.

To start with we looked through a presentation which we looked at different designs and how they would of been printed.
From this we looked at some samples of litho, digital and special finishes from professionally printed work that had been collected. Whilst looking at these samples we were given a linen tester which is like a magnifying glass and lets you look at the print in very high detail to see the process being used and to determine the print process used.
This was very useful and helped me understand how to identify the processes better.

With CMYK prints you can see the actual CMYK dots that make up the image
With spot colour, this is a solid colour that isnt transparent and isnt made up from a mixture of CMYK dots. (it looks like a vector would on illustrator).
With monochrome and tints you can see how the two colours blend together to make the overprint effect.

From this exercise we are to determine which process has been used on the printed samples we brought in:

This is digitally printed as you can see the CMYK dots that make up the colours within the magazine.

Again this is CMYK, alot of the design is in half tones as you can see it is only a 2 colour print with tints used.

This again is CMYK, which i thought the red looked like it could of been spot colour, but when looking at it closer you can see the CMYK mixture that makes up the red colour. This is a 2 colour print as the background isn't white or the stock colour, because again you can see the CMYK dots that make up the colour.

This is a mixture of CMYK and spot colour, the blue around the alpro logo is a spot colour, because it is alot more vibrant than the rest of the print and it is a solid colour, which is needed as it is overprinted on top of the green. The rest of the packaging is CMYK.

When i first looked at this i thought the yellow was a spot colour, which i was right when i looked closer, but the light grey is also a spot colour which is used throughout the publication on the body copy. When you get into the publication the yellow is continuously used along with the light grey for text, but the darker grey headings are CMYK along with the images.

Collect different samples of stock which are:
- coated
- uncaoates
- bond
- wove
- paper weights
