Clear Dry Ink

Apr 19, 2013 2:24 PM

I am trying to use clear dry ink using photoshop and indesign. I have followed every instruction that I can find and have yet to get it to work. There has to be a missing step!!! Below is what I have been doing...This is for a Xerox® Color 800/1000 Press.

 

Sorry this is messy...I copied it from a brochure....

 

Anyone that can help? Thanks!

Creating effects in Photoshop

To highlight an area of your image with a
soft edge and/or a gradient fill, add a spot
channel for clear to your Photoshop file. Save
it as a TIFF or PSD file and place it into InDesign
on the clear layer.
Creating a spot channel in Photoshop:
1. Create a new path or select a shape.
2. With your shape selected, add a new spot channel
a. Name the new spot channel, use the same
name as your clear ink swatch in InDesign.
b. Select Color > M 100% or the same color  chosen in InDesign
c. Select % value if desired.
3. Save as PSD or TIFF with spot color included
4. Place into InDesign on the clear layer.
Setting up your InDesign file
1. Add a new layer in the layers pallet and
name it Clear.
2. Move the clear layer to the top in the
layers pallet.
3. Add a new color in the swatches pallet and
name the swatch
Clear. This is the default
in some color servers. It’s very important
to use the same swatch name across all
applications you might use. The swatch
name is case sensitive.
4. Designate the Color Type as  Spot.
5. Set the Color Mode to CMYK: 0/100/0/0.
You can choose any of the 4 process colors
and set it to
100%.
6. Assign the color  Clear to fills and strokes of text or shapes created in InDesign and move them to the clear layer.
7. To print clear over an image, text or graphic,
set it to
overprint so it will not knock
out any image below. Select
Window >
Attributes > Overprint Fill and/or Stroke
.

    It looks like the Xerox 800/1000 is a CMYK printer with and extra toner channel and that channel has to be named Clear (case sensitive). The directions you posted for setting up a Clear spot channel are confusing because there are unnecessary  steps and the reference to process magenta  could throw you off.

     

    You only have to set up a spot channel in Photoshop if you want to apply the Clear toner to part of a placed Photshop file. Here I might want a coating over the ampersand image but not the background, so I make the selection and choose New Spot Channel:

    All that matters here is the name "Clear". The Color can be anything and doesn't need to be a process color as the directions imply

    In InDesign you don't have to set up the spot color as described, simply place your image with the saved spot channel and the Clear color will be created:

    Here I've turned off the Clear spot plate in Sep Preview:

    Rob, How would you handle the overprint, though, if you wanted to add spot varnish over color in the Photoshop file? I've used spot channels once or twice in photoshop, but never with the intent to overprint, and I'm not sure that it will work without two images.

    overprint by default?

    In my example the spot channel is overprinting—to get a knockout I would have to select the spot area and delete the CMYK pixels, which I obviously wouldn't do for a varnish. In Photoshop you have to manually cut out knockout areas.

     

    The ID Sep Preview shows it as a overprint:

    So if I want to varnish the entire image I wouldn't need the PS spot channel, but I do have to pay attention to the ID object's Overprint setting, which by default is unchecked and knocksout:

    Could you open your document and screen capture your Swatches and Separation Preview panels? Like this:

    Screen shot 2013-04-22 at 10.48.13 AM.png

     

    Then we can be sure it's not a problem with the color setup.

     

    Looks like the Clear spot color has to be mapped correctly at print time. Do you have this? (page6):

    Are you trying to respond by email? If you come back to the web page you can try embedding your screen caps inthe post using the camera icon, like this:

    I finally found an old file someone had done. Everything was the same except for the word "clear".

    See my #2

    Add the spot color and a new layer....both called clear.

    Name's still going to be case sensitive in Photoshop.

     

    You don't need a layer, in fact you can't apply a spot color to a specific layer.

     

    If you are using the pen tool you have to turn it into a selection before you make the Spot channel. Like this:

     

    Select your path in the Paths panel and click Load Path as Selection

    PhotoshopScreenSnapz002.png

     

    Make the spot channel for that selection

    If you can get it to work from InDesign then it must be something in the Photoshop print driver

    Actually I've never tried printing 4-color plus spot separations out of Photoshop—I'm not seeing a way to do it to my Postscript printers. Try saving as Photoshop PDF (PDF/X) and print out of Acrobat Pro

    I read this thread since it has started, and I wonder how you want yo use a spot channel in Photoshop… Why don't you create a clipping path in Photoshop, and import this file in InDesign, but without any mask. Duplicate it, with a zero offset, and on this duplicated image, make a mask with the clipping path. Convert the mask into a frame, and delete the image, so you keep only a frame which has the same shape as the clipping path. Fill this new frame, with the Clear color and check “overprint” in the Object options panel.

    There's not a problem with Photoshop spot colors in InDesign—they are very easy to make and can include gray values.

     

    The last issue is printing from Photoshop not InDesign.
