remove the background from a signature [Edited by moderator. Was :Poor Technical Support Service]

The top image shows the simulated handwriting, a patch of white and at the left a darker tone with the lettering overprinting it. At the bottom, using the Bend If command with a white layer bellow the image layer, the slider eliminated the tone at the left, and the signature surface which has a texture, becomes pure white and the elegant loop in the letter H and thin lines are maintained. 

If it's simply black on white, use Layer Effects to remove the white.

This sample is RGB/8 mode. Move the sliders from 100% until you get the transparency, save as .png to preserve transparency. Also as a side note, Adobe chat support is about solving technical issues such as printing or display, not techniques. The user support forums here have experienced users who can can help you there.

the main issue is how clear the two colours are; for example white text on black bacground will be much better to work with than blue text on a green background because its hard to tell them apart

another issue is what you want to do with this after its removed... as pointed out already, saving as Jpeg will simply put the background back in again

Hi

Basic instructions are:

• Save in a format that supports transparency: .psd, .gif, or .png. If you save as a .jpeg, the background will return.
• Assuming the background is white, select it and then either delete it or add a layer mask.
• Another option is to Place it into Illustrator and run Image Trace with the option for paths instead of fills, then tweak the paths as necessary.

If this doesn't answer your question, can you post a screen shot of at least part of the signature including the background?
