To create a pdf choose Export from the File menu. Creating a print-ready pdfĪs mentioned previously, whilst there are several other checks you’d normally make before sending your document to be printed, in this case you’ve made all the appropriate ones, so now you’ll export the advert as a pdf. If they are not, you’ll be taking a risk that they will look poor quality. This is what is meant by the Effective ppi.Ĭlick on each link in turn and you should see that for each one the Effective ppi is around 300, which is what you should ideally be aiming for. * The reason they are different is because the image has been made slightly smaller within InDesign, and as it’s measured by the number of pixels per inch of the image, if the image is made smaller the resolution will consequently go up. The Actual ppi is resolution of the image at its original size (300) and the Effective ppi is the resolution at the sized that it’s used on the page (312)*. Its resolution is shown as Actual ppi and Effective ppi. The Link Info for the 1.jpg image is shown above. They also will refer to “High res” and “Low res” images, meaning high and low resolution, again high res normally meaning around 300ppi. Printers often talk of dpi, rather than ppi, but it refers to the same thing. But for printed work, a resolution of around 300ppi is advised. For an image to be suitable quality for on screen work, it needs to have around 72ppi. It is measured in ppi, the number of pixels per inch. Resolution essentially determines whether an image is of suitable quality to print. About resolutionĪs well as checking images to ensure that they are not missing, not modified and have a CMYK colour space, you will also need to check their Resolution.
Leave this for now, but later you’ll explore a specific issue that can arise with this type of image. Click on all of the other jpg images in turn to check that they all are too. To see more information about the 1.jpg image, click on its name in the Links Panel.Īs you should be able to see from the screenshot above, the Colour Space of this image is CMYK. That is essentially all a digital photograph is – many thousands of tiny squares, each one capable of having its own unique colour or shade. ** You’re probably familiar with the term pixels – if not, it means the tiny squares of colour that make up a digital image. * I say ideally because even if the images are not in CMYK, it’s possible for InDesign to convert them when creating a pdf, as you’ll discover later. As digital cameras and most scanners work in RGB (like monitors, they work with light rather than ink), the majority of the images you will come across will probably be made up of RGB pixels. This means that every one of the thousands or millions of pixels** that make up the image contains four pieces of information: how much Cyan, Magenta, Yellow and blacK. If you are creating a document which will be printed in Process Colour, any image you place into InDesign should ideally be defined using CMYK*. As a general guide, anything you produce that has a colour photograph on it will be produced in Four Colour Process. If you look on the spine of a newspaper you’ll probably see the letters CMYK, or possibly little squares or circles printed of those colours. This works by printing the four process colours, Cyan, Magenta, Yellow and blacK (hence CMYK) in a close arrangement of tiny dots in combinations that can simulate millions of different colours.

The majority of all commercially printed work is printed using Four Colour Process (alternatively called Four Colour, CMYK, Full Colour, Process Colour). As before, this should not be the case for these images.

Later on you’ll learn how to modify images in a way that ensures InDesign can keep track of them, but for now, all you need to know is that if an image has been modified without InDesign knowing, there will be a yellow exclamation mark icon in the status column next to it. The other preliminary thing to check with the links is to make sure that they haven’t been modified since they were placed into InDesign. The first document you’ll prepare for print has essentially no problems with it, but you’ll work through it to get used to some of the different concepts, terminology and areas of InDesign that you’ll need to become familiar with.

You’ll work through a series of documents, each of which will help demonstrate some different things to be aware of when you’re sending a document to be printed.

You’ll need a CC version of InDesign to work through the exercises - if you don’t have it, you can download a 30 day free trial version from.
