Software Workshop 4 - Practice before print.

This is the last session of workshops, for What is design for print?

So far we have looked at Photoshop, Illustrator and Indesign.

This session is going to be about putting the things we've learnt into practice and so we can test how much we've learnt.
The aim is to creating something using the resources in the shared user file that will be suitable to send to print.

We were given this Indesign file to go over and check.





The first thing we noticed that was wrong was that the tree image had no link to it so it would cause problems when printing. To resolve this issue you would have to find that image and save it in the same file as the rest of the images to make the link.


Secondly, the first page of the document hasn't been bled off the page like the others and the tree image extends further than the bleed will allow so its again not printable.


Thirdly the number of printing plates was too many. The specification for this document allows just 5 inks and there were 2 extra spot colours which would need to be deleted from the swatch palette.


The fourth mistake was that the colour blue being used on the third page of the document is an RGB colour not CMYK which means it will come out differently when printed. You can change this by double clicking on the swatch and change the colour mode to CMYK in the pop up window.


The fifth, sixth and seventh mistakes are all to do with the images of the birds on the second page of the document. 


Bird 1 has been scaled down so the effective resolution has gone up which causes problems when printing, this needs to be amended in Photoshop. This means your working with an unnecessarily big files and that Indesign has more to do when sending it to the printer.


Bird 3 is still in RGB colour mode not CMYK so the colours will not print the same as you see on screen. You can change this by opening it up in Photoshop and 


Bird 5 is using the wrong resolution, its still in 72dpi which is for screen wen it needs to be 300dpi which is for print. This can easily be changed by holding down the alt key and double clicking the image and it will open up the image in Photoshop where you can change the resolution in the image size window. However Photoshop can only work with the original image so re-scan it or upload it.


Lastly, the text on the bottom of the last page is using the registration black instead of the normal black so that text will be printed on all the coloured plates which isn't what you want. The registration black is just for trim and print marks.




A lot of problems are cause by badly prepared images in Photoshop and incorrect application of colour in the document.




PREFLIGHTING (last minute checks before takeoff)


You can leave it as an Indesign file which is up to the printers, they may say its fine to work with. You will have to send all the images and fonts used on the document as well otherwise the document wont work when they try to print it. The best way to save them is to keep them all in folders, Indesign will usually create these folders for you.


Before printing you need to 'Package' your file, this will gather all your images, fonts and links along with your Indesign document. Before you click the package button in the pop up window you are presented with lots of information about the document the images, the fonts etc so you can see if everything is ok for it to go ahead and be printed. It will give useful information on where the files are on your computer so you can find them and also where they are in the document. This is a good opportunity to go over everything to make sure its all in check.


Saving as an Adobe PDF


File - Export - Abode PDF for print - save - Adobe PDF presets - press quality - export


it may take some time to export if there are lots of images or lost of information being compiled into the file.
