Flooding Letterpress Ink

This post shows a card we letterpress printed for Grass Fed Cattle Company designed by a good friend and design mentor over the years – Michael Skjei. We love the commitment to local farmers and free range meats. If you are local, give these guys a try.

We seem to be getting an aweful lot of requests to print business designs with floods of solid color. It can work on letterpress – with a couple big caveats.

Will the color be consistent?

We will have a wider range of ink density variation in the print run than an offset press. We do not have computers sitting on press monitoring this, it is all by eye. We matching to a print at the beginning of the run and keep it as a target, adjusting as we go to keep everything as close as we can. But there will be variation.

The heavier the ink density, the more difficult it becomes to hold the detail of fine typographic detail. So if you are flooding, more robust type works better.

Will my color print solid?

This depends on the type of stock and the color. Lighter colors and smoother paper stocks generally print with less “saltiness” in a solid area of coverage. Since letterpress prints with pressure, we are much more subject to the texture and formation of the sheet of paper to achieve an even solid.

Will there be impression on the text?

Generally, no there will not be impression. Letterpress works best with text and artwork that is pressing into the sheet. If you are looking for impression while flooding a color, this is not a great use of letterpress. Notice how the logo and gray ink have impression, the green flood of color does not.

Is the cost the same?

A flood of color takes much more time to set up on letterpress than a card that has text only. Generally, this involves making ready the ink fountain and double the amount of makeready sheets to get color up to speed. Since we charge based on press time, printing a flood of color will cost more thanĀ  printing a text only design.

However, most small offset printers can’t make a 160lb or heavier sheet of paper run through their press. So that leaves letterpress as a viable method to print to handle these heavier stock thickness. You have to get on a much larger offset press to touch that kind of stock thickness, which means also means bigger quantities and costs.

So yes, we can print solid colors IF you are comfortable with the variations that are inherent to the letterpress process.


  • Thanks for this post. I was actually wondering today if this was possible, and am actually really please to know that the flood doesn’t cause an impression, as I’d like to print something with an impression on only one side. So fantastic, and so informative.

    Love this blog. Thanks for giving designers an insight into letterpress printing.

  • I should clarify that you don’t get impression on the text because the whole side of the card is being pressed and bleeds off the edges. There is certainly pressure being applied to the sheet, and it will iron out any impression that may be on the front side of the card, so we always print the flood first.

  • Wow! The flood looks great on these pieces!
    We’re letterpress printers too, and are always wary of doing floods or colorblocks in designs we get. We do the same thing as you with having a “key” piece that acts as a guide or target for reference throughout the run. Maintaining a consistent opacity throughout the run is always a challenge…

    Two questions…
    1) did you get this level of opaque coverage on one pass through the press… and do you ever have issues with the piece sticking to the form when using this much ink? Any tricks? We print on a Heidelberg windmill which I think you guys also use…

    2) The front side looks like there’s some impression in the design, yet no “matting” of the paper fibers on the back flooded side, where the impression from the front side would be tempted to push through during printing. At first I thought you guys did a laminate of two pieces, front and back, but it sounds like you didn’t. Is it just your paper choice, and careful application of “just the right amount” of impression that got you looking this good here? Or do you have any other tricks you’d care to share?

    Speaking of laminating… Do you guys ever do post printing laminating of sheets together? Do you have any glue / laminating solutions that you like? We’ve been curious about this kind of thing, but haven’t had to do it thus far….

    love the blog, btw! big fans! Your stuff looks great.

    Thanks,
