Folks

I have a problem in Photoshop 6.01 on running on OS9.22 that I have never had before.

If I make a foreground colour of 0,64,100,0 and then fill an area with the paintbucket the colour in the ‘info’ window shows it as 1,64,100,1.

I have color managment off. What is going on?? This has me baffled

Thanks

Was the file ever a JPEG?
Why use the bucket and not a curve?
What’s the blending mode of the paint bucket?
Why are you working in CMYK? : )
Why do you care about 1%?
What do you think "color managment off" means?

I think you’ll survive! : )

1. The file was a jpeg but has since been saved as psd file

2. The bucket I believe is the correct tool to flood a background

3. Blending mode is ‘Normal’

4. I work in print therefore CMYK is correct

5. I care about 1% because this image then sits in Quark on a larger background that is 0,64,100,0

6. Not sure what you mean here. Off is off isn’t it?

I’d make the quark background a picture box filled with a small cropped area of the photo. The resolution is not important for flat areas, so you can stretch a small file across the page.

The 1% is a Photoshop bug in documents that were once JPEG.

Wasn’t the scum dot problem fixed in 7.0.1?

And you don’t need the paint-bucket to fill a background (unless you need its built-in magic wand feature).

Just fill your foreground swatch with the color you need and hit "Option Delete" to fill the selected area.

Change the color engine in the color settings. For sure the Heidelberg color engine creates a scum dot. It could as well be the rendering intent along with a bad or poorly made profile.

Yes–the patch for 7.0.1 fixed a scum dot issue with JPG files as well.

You may think so, but that is not the case, "You can’t turn CM off."

Unless you’re working in a cave, and never open anyone elses files, and never have color problems, you may be wise to turn CM on and figure what’s actually going on…
