This is the plan adopted by professional photographers for mounting prints. Immerse the trimmed prints in water tor a few-minutes and then place face downwards one on the other on a sheet of glass. Squeeze out the excess of water with a roller squeegee and blot off the surface. Brush over the back of the print with cold starch paste, free from lumps, taking care that the edges of the print are well covered. Raise the print by the corners, lay it in position on the mount, place over it a sheet of fluffless blotting paper, and roll into contact. Continued or heavy rolling is unnecessary. If too much starch is used it will be squeezed out around the edges of the print; if too little is used the print may not stick at all. Should any starch spread on to the mount it is sometimes advisable to remove it by sponging over the whole mount. In mounting, first estimate the position of two opposite corners, then lay the print down so that it touches the mount diagonally. Starch paste more than one day old should not be used, and all lumps, even very small ones, should be carefully removed.

Platinotypes require more starching, and do not stick if the undried mounted prints are laid together.
