Packaging your files
In order to send your files efficiantly and complete you must package your files. If you are working in InDesign you will need to make sure that your file is properly linked to start, then go to file > package. This will put all of your images, fonts and design in the same folder. You will then want to Zip or Stuff the folder to compress it for quicker delivery.
If you are working in Photoshop it is best to have all of the images (TIFF or PSD) in one folder. DO NOT compose text in Photoshop as this program does not render text properly when printing to inkjet printers. You will then need to Zip or Stuff the folder for quickest delivery.
