You should only submit flattened, or layer-less, versions of these files as well (jpg's are automatically flat)
To flatten a file, open it in Photoshop and go to "File" and choose "Save As..."
Choose the file type you want to save the image as, but also uncheck the "Layers" box
Name and save it to create a flattened file
Flat files ensure all elements in your file, such as special fonts, will be included in the print
File Naming
It is imperative you include your name in the file before submitting it to Media Services
Large format prints are manually charged to your Papercut account, and we won't print a file if we can't charge an account
For instance, if you submit a file called "Image001.pdf", we can't determine who submitted that file, and it won't be printed
However, if you submit a file called "Barnaby Jones Project 1.pdf", we know who to charge and will print that as soon as possible
If you have multiple prints, you can save time by simply putting all of them in one folder with your name, instead of naming each one, and then submitting that
