If working with a lot of text, clicking 'Primary Text Frame' places text boxes on every page.
Indesign applies colour in the exact same way as Illustrator, working with coloured vector shapes.
Colour can also be applied in a stroke.
Indesign also has a swatches pallet which allows designers to consistently work with colour.
The indicators represent that the colours are CMYK and global swatches.
Swatch options box.
When a colour swatches values are changed all the colours rendered in the selected colours update with the change.
To find the tint of a colour use the drop down menu found on the swatches menu.
For spot colours create a new colour swatch and choose from the drop down menu.
When the image is imported from Photoshop to Indesign, the program retains colour information such as the specific spot colours used.
Important Photoshop Considerations;
- Resolution - (300dpi).
- Actual size - Images at correct size.
- Colour mode - CMYK or Spot.
- File type - TIFF or PSD.
(If working with transparency then you should work with PSD file type)
Important Illustrator Considerations;
- Colour mode - CMYK or Spot.
- File type - .AI
(You can also copy and paste artwork from Illustrator into Indesign to save time)
To preview the colour separations follow: Window > Output > Separations Preview.
The menu allows designers to see what the individual colour layers look like.
This process can be used to create individual layers for screen exposure during the screen-print process.
There are some unused colours found in the separations pallet that are there because they are available in our swatches pallet. You need to get rid of these as if sent to print they could be used while printing the final outcome, this could affect the colour and cost of the print job. It is good practice to delete all unused swatches to save confusion.
The print options box gives designers the options to include important marks such as crop marks and page information.
To print individual layers follow: Output > colour > Seperations.
This allows you to choose what individual colours print.
If only one of these colours is selected then only that colour will come out of the printer. Useful for screen-printing.
Halftones are measured in lines per inch, 150 halftone dots
40 - 65 good frequencies to use with silk-screen printing.
The colour separation process only works with digital laser printers.
You can also open the colour separation menu by following: View > Overprint Preview.
When selecting one spot colour where there is an overlap Indesign will 'Knock out' the colour.
The default for a black ink is to overprint, darker colours should be overprinted.
Overprints can be used to create a third colour during the printing process. To view colours how they would look when over printed follow: Window > Output > Attributes.
You must be in 'Overprint Preview' to see any of the changes made.
Red overlay indicates that colour has exceeded the ink limit.
When preparing work for varnishes or spot colours use an overlaid spot colour to ensure that it does not affect the CMYK colour channels.
By combining tints and overprints you can create a variety of different colour variations.
