The paper quality is of utmost importance when it comes to alternative photographic printing processes. Once that is in place the chemicals, coating and acidification of paper need too be placed in order and done with care and efficiency for a good print.
There are many little details that need to be taken care of while creating something. This manual rendition of visual thinking in forms of alternative photo printing techniques throws light on all the things that go into the craft behind the output of the final work of art. Discussing paper quality, an important component for your output, with the residents….
Artist Watercolor Papers are extensively used. A 200 gsm is ideal but anything close to 160 gsm should also be fine. Also make sure the paper is of archival quality. Hot Press and Cold Press are two different types of Papers used for these processes.
Hot Press :
A smooth surfaced paper created by pressing a finished sheet of paper through hot cylinders is known as hot pressed. Hot pressing results in a smoother surface than cold pressing which flattens but leaves a slight texture.
Hot pressed papers are often used by artists who want fine detail whether using pen, pencil, or paint. The medium flows more smoothly across the paper. Hot pressed papers are good for photographic quality prints whether glossy or matte.
Cold Press :
Pressing the paper through rollers at the end of the papermaking process smoothens the surface for printing and writing but still leaves some texture; unlike hot pressed papers made using heated cylinders which are smoother than cold pressed.
So far, hot pressed has been a preferred choice. Tashi mentioned that it retains more finer detailing since the paper is smoother with lesser texture. Unless there is something you have particularly in mind with textures on the paper to merge with your photograph or if you’re doing the Gum Bichromates for which you could try the cold pressed.
