we had a lecture with from evolution print.
they are a print company
min 70gsm max 450 gsm.
talked about uncoated orints - images are flatter because when dot hits paper theres a spread of ink so less sharp. silk and gloss printing much sharper. 80gsm gloss will feel really thin.
litho - plate printing in cmyk, better quality but more expensive and a limited process. they use veg based inks. can do 5 colour print - very costly.
charge based on make ready charge - set up and running of machine. also plate costs for each colour.
digital - sora3 is max size in commercial digital print. digital uses powder based inks. also everything has to be full colour so spot colours might look different etc.
job costed using a clip charge - charged per sheet (5-10p for one colour one sided, 60p per sheet for one colour 2 sided). cant run a 5000 job on digital - too costly.
things designers get wrong -
- bleed - 3mm. include ticks, strokes, crop marks.
- business cards need to be layed separately
- booklets - send as single pages - they put together. if perfect bound with 5-10mm send the cover separate so they can work it out.
- send in pdf and original format.
- make sure in cymk.
- transparencies only work in over print
- any cuts or perferations they need to be set as over print and spot colour so can see the difference. set each one as a different spot colour in a separate file.
- image size - dont use 60mb images for smaller frame. keep at 300dpi and use same size image as frame or try to.
-if doing a booklet work in 8,16,32s not 4s.
.work and turn - each side matches up with the other - when one is done then its flipped and printed again.
.sheet work - 8 plates - for many different print jobs on one.
they dont do spot varnish or laminating.
