Converting a Color File to Grayscale in Illustrator

In order to qualify for black & white pricing on the plotter printer (Epson T5270D), your image must first be converted to grayscale. If your image is submitted in color, you will be charged for the color price.

For the best results, you should always work from a duplicate file. Illustrator preserves editing capabilities but to keep yourself organized, it’s in best practice to save a separate grayscale IC print file.

» Open your file in Illustrator
» Select all of the objects whose colors you want to convert.

To select all objects in a file, choose 

Select > All. (To deselect all objects, choose Select > Deselect)

» Don’t forget to unlock all layers & objects on your artboard! 

Object > Unlock All

» Choose Edit > Edit Colors > Convert To Grayscale

NOTE: Use the Edit > Edit Colors> Adjust Colors command to convert objects to grayscale and adjust the shades of gray at the same time.

Your Illustrator file is now ready to save as a PDF file! Happy printing 🙂
