Which file format(s) should I use when I send the final file?

IN Contest

The customer shouldmention in the contest brief which format(s) they want their file to be in. If they don’t, you can ask them about it in the comment section of your design. You can also ask about the color mode to be used in the design and other additional information.

It’s important to use a CMYK color mode with a resolution of at least 300dpi for printing purpose. If you are using a vector program, like Adobe Illustrator, you won’t need to worry about the resolution. File formats for CMYK print designs are stated below:

● PDF – Portable Document Format
● Adobe Illustrator (.ai), Adobe Photoshop (.psd) or InDesign (.indd)

You can use RGB color mode at 72dpi resolution for electronic purpose. File formats for RGB computer-based designs are stated below:

● PNG – Portable Network Graphics
● JPEG – Joint Photographic Experts Group

Besides these files, you are required to give the customer editable files. PSD (Photoshop) is a raster-based editable file while AI (Adobe Illustrator) is a vector-based file that must be used for logo designs.
Make sure you provide the following file formats in CMYK mode when you’re designing a logo:

● Adobe Illustrator (AI) file
● editable PDF

Please include a PNG in RGB mode for web use when you handover the final logo file to customer.
If you use CSD (CorelDRAW), you should also provide the customer with an editable PDF or convert your file to AI.
If you’re asked to submit various files at once or big sized files, you can convert them into a .rar or .zip file.
