OUGD504: Brief 4- Print Workshop 3

Indesign: 

When creating something for commercial print should include bleed to allow printed images to be trimmed correctly. The slug area provides a larger area which can also be printed, which are useful for other information such as fold marks. 

Colours can be added through the colour section, however swatches are more consistent to apply. Global swatches can allow colours to be changed across a document:

Spot colour pantone solid coated: 

The colour is not shown through CMYK values, it is named as a specific swatch. When creating a limited colour palette it is worth knowing that cmyk uses four inks to print one colour but it could be cheaper to use one ink as a spot colour to use tints. 

Images should be prepared correctly before importing them into indesign. The image should be prepared at actual size for print. The images should be made at 300dpi to ensure correct image quality for print. Images should also be saved as CMYK or greyscale they should be saved as tif or psd files, jpeg should not be used. 

The spot colours on the images when placed into the document appear in the swatches palette, this means that the colours can then be used for other elements such as type. 

Colour added to the foreground of a b&w image is a way of creating a mono tone in indesign. 

If you click onto the image and select a foreground, the image becomes that colour much like a mono tone. This only works with greyscale tif image files. 

This is a tool which show you how the image will be separated by colours. The positives can be used in conjunction with screen printing and this process is used within indesign.

Notes can be added when sending to the printers which is useful for commercial print. If sending work to print, fonts and type should be changed to outlines or send the work as a pdf instead of the original indesign file. A package file includes images and all the different elements relevant for the file to send for print. 

The part that says "frequency" is basically half tone dots which mean that one ink can be used across all of one colour. More dots mean a darker or more intense colour, with less dots being the opposite. The exact same process can be used for screen printing. On the section which says crop marks, page information can be added which is good for telling you which one is for each colour. 50-60 frequency for screen printing, the angle for screen printing should be 15 then, 75 .... 100... 155. Spot colours are printed separately.
