Hi,

I’m having trouble with reviewing my pattern tiles (1890 x 1890px at 150dpi).  I am getting a pale line throughout my pattern in the pattern layer and the pixels running on the edge of my tile seem to lighten automatically.  Even though the change is quite faint (as shown in the photo), it’s not suitable for printing.   My pattern tiles are 1890 x 1890px at 150 dpi and the colour of the pixels along the edge change which is becoming very frustrating.  What am I missing?

Thanks so much,

Liz Hussey

Hi,

  1. Add a channel mixer adjustment on top.
  2. select a alpha channel
  3. set offset to 100%

If you upload the actual document i can show it with that example as screen recording.

Hi Liz,

 

as your pattern has transparent areas, I’ve adjusted the workflow a bit.

  1. open the file
  2. add channel mixer adjustment on top
  3. select alpha channel
  4. set alpha to about 112%. This lifts the partial alpha in the „pale line“ area so they vanish.
  5. As a side effect, the anti-aliasing of all edges changes a bit, too.
  6. to compensate, add a levels adjustment 
  7. select alpha channel
  8. move gamma slider to about 1.2. This brightens the edge area a bit.

in the video I copied the channel mixer by mistake, and deleted it. You can skip this step 😄
