Getting Fiber Based Paper Flat

[koraks]

Believe me it does work and I must have done dozens of prints this way with no damage what so ever.

I've also done dozens of prints this way and it does not consistently/effectively remove the curl from most prints, especially the waviness along the edges remains, and on prints larger than around 5x7". It may depend a bit on the paper used and how it was cut (paper has a 'direction' and it matters here). The clothes iron approach works to an extent, but it's not super effective, overall.

I get nice flat prints from my Pako drum dryer. Fiber prints simply will never lay as flat as a RC print. For display I usually dry mount, keeping unmounted copies of the mounted print in reserve.

Professional frame shops have more options than dry mount.

I do it like this:

Dry face up on drying screen.

Flatten in heated dry mounting press for several minute, face up, covered with release paper.

Avoiding edge ripple requires that the print be well surrounded on all sides by the release paper and press platen surface, and that the temperature be sufficiently high. I use something in the range of 225-250F.

Yes. I always use release paper in my press too!

I should mention that, when doing this, the back of print is resting on a piece of mat board on the press, not the press' rubber pad.

Exactly. I sandwich my prints between 2 sheets of mat board with the release paper on top of the print

I agree to a point, but when I used FB paper I also used a heated dry mounting press and the odd wavy edge didn't matter one iota. The shellac tissue sorted that out when it was stuck down. A badly curled print was next to impossible to tac down accurately so that the print was attached to a mounting board where I wanted it.

Even the edges could be flattened if after the main sheet of the paper had been flattened by the well tried and tested straight edge on the back of the print.

Unfortunately it is the nature of the beast (FB) paper that it will be next to impossible to get it to dry completely flat unless some sort of heat such as a heated drying/glazing bed is used. Even then the paper will try to take on the curl of the heated bed - bring on the straight edge to get rid of that.
Even when I was using a rotary drying drum at work in the 1960's with single weight glossy paper there was still a residual curl which took a couple of days to loose naturally.
Been there, seen it, done it!

I understand that, but most of the time I want a print to be flat also if it's not mounted or glued to anything. This is possible in a number of ways, and a clothes iron gets you there to a certain level, but not perfectly so.

Taping to a rigid support and then allow it to dry will make FB absolutely perfectly flat. Proper use of a heat press can also accomplish this, but technique/procedure matters. Ferrotyping will also work, but of course affects the surface sheen which may or may not be desirable, and there's of course the technique issue that results in many failures until you figure something out that works.

Anyone used a T shirt heated on design press?
