    Carbon Watercolour paper not flat

    Hello,

    I glued a watercolor paper with a gelatin layer to 5% with a coating rod.
    I print the Carbon.
    When paper is dry carbonl with the image, the paper is not flat, gondola.
    I have very difficult thing to get a paper perfectly flat when it is dry.
    Have you a method to make the paper really flat?

    Thank you for your help

    A dry mount press is the way to do it. I also struggled until I found one nearby. Canson Montval and Hahnmule Bamboo Mixed Media warp much less than pure cotton rag papers.

    Thank you,

    Can you recommend a brand or type of dry mount press
    If you have a picture or a link to see the good press to buy ,

    Is it possible to use a hot press without damaging the image carbon ?

    Thank you for all information

    The differential expansion between the paper and the gelatin with humidity is the usual cause for the curl. You can help it a quite a bit by sizing the paper thoroughly with gelatin or one of the commercial sizing materials. It's easy to do, and it only takes a few minutes. Dry mounting will pretty much cure the problem, but many people like to have the paper free of the mount.

    I have one of theese, http://www.bhphotovideo.com/c/produc..._Mounting.html
    It was a small fraction of the new price on the local verson of ebay. They are very heavy. So far I only use mine to flatten prints.
