Slug (blue outline) - Is a lot larger and used for printers marks. Things that are used in the print process but aren't part or the design or layout. The slug area is useful for fold marks.
White is called paper, this is more appropriate because you don't print white. It will be the paper it prints on. Global swatches allow us to make consistent changes as it changes everything that colour. Everything that is purple changes to blue when I change the purple swatch to blue.
Tints also allow us to change. It is useful for a large print using only one colour. I can save these to my colour swatch list.
All these different tints will print with one colour.
Photos
1. Actual Size - if an image is put into indesign and then enlarged the pixels spread and the image becomes distorted. It lowers the resolution and won't print well.
2. We have to work at 300dpi to get good print quality.
3. CMYK or greyscale.
4. Save as Tif or PSD not JPEG! the quality is small.
To give the work to the printers it either needs to be given as a PDF or as an indesign file with the fonts and everything etc...
Making Images The Right Size in InDesign
clicking on the image and the link button on the right.
It shows the scale is 46.7%
Clicking on the image > edit with > photoshop
In photoshop click image details and change to percent. Type in the percent shown on InDesign and save.
On InDesign it will then change the scale to 100%.
Inserting an image with spot colours
Here I have inserted the image from photoshop which is used from 2 spot colours. The two spot colours appear on the bottom of our colour swatches.
The same can be said for illustrator with vectors.
Applying colour to an image in InDesign.
Grey scale tif file only!! Selecting colour and filling the box. This doesn't work on images as images fill the whole box. It allows you to work with spot colour in InDesign and not have to go into photoshop.
This also works by using the content grabber, as it then changes the pixels from black to blue.
What Happens Next
Colour Separations
Window > Output > Separation Preview
This allows you to preview the ink. The preview looks just like the colour swatches but they are now inks. The eye symbol to the left of the colour allows you to turn off a certain colour. This is a great way to check the spot colours are separate to the CMYK print.
Once I remove the Cyan it shows what it would print like without Cyan.
If printing as a PDF go to File > Adobe PDF Presents > Press Quality
This will then print it to the highest standard.
Before Printing File > Package which will package the whole design and all its elements from images to fonts. It will also include a pdf version which is useful so the printers have a final layout to work to.
You can fill in your details so that they can contact you.
It will save everything in one file. Including IDML files which allows it to be opened on any version of the software.
This is so useful not only for sending off to printers but to keep a final of your work together before working on another computer.
On the printing section you can change it to separations which will then print a positive for every colour. It is important to delete any unused ink swatches as these will print a positive which in the long run will cost. This method can also be used for screen printing. As it will print black and white with each colour being a separate layer.
Half tone dots allows us to print many shades of one colour with one pot of ink. The larger the dots the less space between them so it creates the illusion of a darker colour. Less frequent dots increases the white in between which gives the illusion of a lighter colour. The higher the quality of print the higher number of dots used. 4 grids of dots for each CMYK colour. The dots are rotated so that it covers the gap of the previous one - this is to get ride of the moiré effect.

The first colour angles 15
The second colour angle 75
The third colour angle 105
The fourth colour angle 155
It is unusual to have more than 4 colours, as spot colours are printed separately.
When separating the inks InDesign will knock out colours when overlapped. It does this so that there is no mixing of the inks. Below two overlapping squares of yellow and cyan. When I remove the Cyan it gets rid of the yellow under the cyan as well.
To stop the colour from being knocked out use the attributes. This can be useful for screen printing as it creates a 3rd colour, this can save on ink during the screen printing process.
