Collotype Surface View
Surface Sheen
Collotypes can have a variety of surface sheens depending on the paper used and the purpose for which the print was made. Prints could be made on coated, baryta, and uncoated paper.

What to look for: The surface sheen may vary depending on whether or not the print has a surface coating. No surface reflectance (matte) may indicate the print does not have a surface coating while some reflectance may indicate a coating is present.

Surface coating applied over ink image.
Semi-gloss surface sheen indicating the presence of varnish or shellac.
Surface Texture
Surface texture will vary greatly and depends upon paper type. Because the collotype is a planographic process, ink in the image will be level with the surface of the paper. Like lithographic prints, collotypes will not have a plate mark, unless a false plate mark has been applied.

What to look for: Ink level with paper surface when viewed with raking light; lack of true plate mark.
Ink is level with surface of paper.
Paper texture is visible in raking light.
