    I took this a couple weeks ago while out by the local strip pits. Summer in the midwest, going to strip pits, listening to music, and some light drinking. *sigh* Always a good time.

  • Best method of feathering

    I have yet to be successful in getting something to print feathered to complete transparency. What looks feathered from 100% to 0% onscreen ends up like 100% to ~5% or so and is obviously clipped at the image's edges.

    When making a selection on an image in PS it's obvious that feathering doesn't work from the "inside" or "outside" of the selection so I figured it must work from the "center". Say I have a 4"x6" image at 100dpi (to keep the calculation simple) and want to feather at 50 pixels. I'd think that a 3.5"x5.5" centered selection would feather to 0% exactly at the images edge (since each boundary of the selection would be .25" away from the edge and feathering 50 pixels at 100dpi) but this is never the case on press.

    Help?

    You could alway use a white layer under neath to see you you like your fade/vinette, Use your info tool to see if the the cmyk values fall to zero. Are you printing out of photoshop? Sometime I delete the feather selection twice to make sure it fades out smooth. You can expand your canvas a little to make sure you have a bit around your picture. There are about a million ways to do it. I think there might even be an default action in PS that does it for you to some degree.
    I don't make mistakes. I thought I did once but I was wrong.

      that's just an issue you will have to face with standard printing... your eyes will always be able to distinguish where a line of dots stop when trying to fade to 0%..

      Instead of fading off to 0%, fade to 5%, so the dots don't stop...

      There is a pretty cool printing process called FM (Frequency Modulated) screening that takes all the vignettes in a document and randomizes the dot patter... instead of lines of dots fading to 0%, you get dots that scatter off to 0% without leaving a visible line...

        doh! That's what I'll have to do. That should work. Thanks Crimson.

        I always print out of InDesign.

        I also tried the deleting twice trick but it never gets it to fully to to transparent before getting clipped. However that won't be a problem using the info tool I'd think. Thanks again!

          Then I'd have to have a page covering 5% in InDesign as well. And I don't want 5% of any color on my whole page unless I specifically want it there. : )

          Yeah, I've seen that technology. Wish we had it here as I can see "honeycombs" from a mile away.

            It appears that I should never have gone down the "feathering road".

            Custom gradient as a clipping path seems to work, although I just printed it on a laser printer, not an off-set press.
