Using colour
To apply colour in indesign, it works the same way as illustrator by adding colour to a shape
Its best to apply colour with the swatches palette for consistency.
The palette has a few standard colours as the default setting for practicality
This icon in the palette refers to cmyk colour
This icon refers to global colours
To create a new swatch its the same as in illustrator
To apply a tint select new tint swatch in the drop down menu of the swatches palette
This allows you to adjust the tint value of the swatch
For spot colour create a new colour swatch and choose from the colour mode drop down menu
Change the colour type to spot colour
The swatch will look like this
Using Photoshop Images
Using a duotone image
The inks used in the duotone image will automatically appear in the swatches when opened in Indesign
This is the same principle when an image is used that has a spot colour applied
Image Preparation
Photoshop
-300dpi
-images need to be made the actual size they are going to be when they are placed in Indesign
-CMYK or Spot colours
-Save as TIFF or PSD (support transparency)
Illustrator
-CMYK or Spot
-Save as AI
-Can copy and paste vectors straight into indesign
Printing an Indesign document
The separations preview allows you see what inks will be printed
You can click on the inks to see how they will be applied when printing
This is the same process to setting up a screen when screen printing. There are referred to as positives.
Its good practise to delete any unused spot colours in the swatch palette to avoid any extra cost when printing
In the marks and bleed section You can add crop marks etc to the print
Page information is good for creating positives for screen printing because it labels the print with the corresponding colours
In the output section you can choose the separations menu to see what inks will be used when printing
Adjust the frequency to adjust the halftone dots
Half tones are measured in lines per inch
High quality images are usually around 150 lines per inch
Silk screen 40/65
The separation process only works on laser printers!
Over Printing/Nocking out
When colours overlap the colour underneath will be nocked out
The default for black ink is to over print
In the attributes menu you can select overprint. This now lets the colour of the shape beneath come through to create a third colour
This can be useful when using a finishing option like a varnish or glue. You must set the type or image to over print to allow the varnish to be applied over the top instead of knocking out the colours beneath
consider the amount of ink that will be used
This can be checked in the ink limit section in the separations preview. If the ink exceeds 300% it will have a red area. This is useful when considering what stock to use
