Image Optimisation -Workshop

In this workshop, we looked at how the quality of prints can change between types of CYMK prints. This is because there are a number of different variants of CYMK prints. One of the things that we talked about changing the quality of the colours printed is what type of paper that is used. Coated paper is brighter because the ink sits on the surface of the page and uncoated produces duller colours as it absorbs the ink more).  I had never heard of ICC (international colour Consortium) helps designers start to get things right when printing, But it makes that there are some guidelines. Colour profiles help us predict what the colours look like when printed. The guidelines are predicted to be seen at midday in London.

Using Adobe Bridge I set my Creative Cloud to work to the colour profiles that are of a most of the standard to printers in the EU  (Europe pre-press 3).

Every image has a colour cast (like a filter, Muddy, green, blue) To work on white as white and black is black, Trust the numbers. A serface white White has a minim of 5% of Cyan, Magenta and Blue in it. 5% is the smallest percent that can be printed whereas blacks are a combination of colours. Combined 320% in on coated paper before it gets messy whereas uncoated is less at 310%. Another type of white is specular white no ink colour of paper or screen.

I then had a go at optimising one of my own photos for print. I choose to do this with a photo I took in June of La Sagrada Familia in Barcelona as I took it in black and white and there’s a high contrast and I thought that this might show the change easier when comparing.

The right being the optimised image definitely has more detail in it that I never realised I had captured as before they were very much darkened. I am really impressed that this can add more to photos than I thought was there.
