How to Set Color on the Back Using Photoshop
Save as a TIFF.
PLEASE NOTE: If your artwork is solid black on a white background like text (no shades of gray), you should save as a bitmap tiff at the resolution of 1200 pixels per inch (ppi). Here’s how:
- Be sure you have created your artwork at 1200 ppi. Go to Mode > Bitmap (You may need to convert to Grayscale and then to Bitmap).
- Set the resolution to 1200 ppi and the Method to 50% Threshold.
- Again, a bitmap TIFF should be used when there is only solid black and white areas in the image. If there are any shades of gray whatsoever, the file should be saved as Grayscale.
How to Set Color on the Back Using Illustrator
To check for images you have placed into Illustrator using the “Place” function, you will need Photoshop.
To be sure that all your vector objects are all Grayscale, you will first need to select all (Control-A Windows, Command-A Mac), and then go to Filter > Colors > Convert to Grayscale.
To double check that all your vector objects have been converted to Grayscale, go to File > Document Info (you may need to select all first) and pull down on the small options menu on the Document Info Palette to “Options.”
In this example all the objects have been successfully converted to Grayscale.
Please note that gradients will not convert using the Convert to Grayscale Filter. You should probably create your gradients in a raster editing program like Photoshop and place them into Illustrator.
