I’m hand tinting a b&w photo in PS
If I print it as a colour image I invariably get unwanted colour cast in the b&w.
I’d like to print with black first then run it through again with colour ink after.
What’s the best way to seperate out the colour?

I’m not sure you will get the results you’re looking for.

The color cast is probably the printer’s attempt to create shades of gray. So even if you eliminated all color, you may still get the same results.

Running the same page through the printer twice is going to introduce the complication of registration.

The guys that are pushing the B+W envelope have all switched to ink in shades of black. This eliminates the color cast and opens up the gray tonal range.

Make a duplicate layer of the photo & do all of your hand coloring on the duplicate layer. When it comes time to print you can choose to print the original image by hiding the colored layer, or vice versa.

Not quite right: if you print with black only, your printer can’t ad any colors!

Right you are.
But the resulting image is not very good.
With color turned off, gray pixels are rendered by the printer as larger or smaller black dots. Turning off color forces the render engine to operate more or less as a photocopier.

Under ‘normal’ conditions, the printer render engine adds tiny color drops to the black pixels to approximate shades of gray, hence the color cast. Turn off the color and the grays disappear.

I never do, but I keep on trying =)

I don’t like the sounds of that, though it makes sense. Do you think my Epson 1280 is suffering the same drawback as a 3 colour printer though, ie. no black = dark mud, with black = a more refined dark mud?

Well, you’d think so. However, whoever is engineering Epson printers is doing a bang up job in spite of the other yahoos there that manage, market, program, service, support and otherwise piss off their customers. Printer good. Company bad. My point is, I put a single dot on a page and ran it through 4 times at 1440 on heavyweight matte and I need a loupe to see if it misaligned. For what I’m looking to achieve here this is not an issue.

True, but even if I print a quad tone I still need to know how to separate the colour from the black/grey for the second overlay print.

I think you missed the point. Unfortunately I was being rushed out the door when I made the post and didn’t word it accurately. I’m creating a hand-tint ‘effect’, so I want to retain the original colour. Just in select locations. Unfortunately masking has been problematic as you might imagine.

Try this…

Layer/New Adjustment Layer/Hue-Saturation
name = ColorTint
move the saturation slider to -100
Repeat
add a second adjustment layer
name = Black+White
Turn off Black+White layer
Go to ColorTint layer
Click Eraser tool
hardness = 0
opacity = 40
adjust size to suit
‘Paint’ over the areas that are to print in color
with opacity at 40, you can make multiple passes over an area to ‘reveal’ just the right amount of color for a hand tint effect.

Print the black ink on run one
Black+White layer = ON
ColorTint layer = OFF
Image layer = ON
Set the printer to Monochrome

Print the color inks on run two
B+W = OFF
Color = ON
Image = ON
Set the printer to Color

I have no experience with multi-pass printing so there may be a gotcha in there…
On the B+W print run, you may have to reduce the opacity on the Image layer because you will be printing the black ink on both runs.

Or you could remove black ink areas from the color print run… Use the magic wand on the ColorTint layer to create a B+W selection; tolerance = 12
anti-aliased = checked
contiguous = unchecked
On a duplicate of the image layer with the B+W selection active, Delete. The ColorTint layer and Duplicate Image layer will then be your color print run.

Good luck

Thanks for the time and effort, but still haven’t got it. Guess I’ll invest my time in tweaking the printer to match the paper. The downside of this is varying colour casts on different papers.
