10th/ 11th Feb 2016 - PROOFING AND REGISTERING





Worked on second stone (above) to proof and then to try and register on the prints already taken from the first stone. A mixture of phthalo blue litho ink and velvet noir ink was mixed but was a bit green - Added some cobalt blue -now a bit grey !!- The image took lots of proofing to come up (15 proofs!)
Registered prints initially using acetate (cadfoil) template and external registration marks made on blocks of wood wedging my stone on the bed.
Printed the stone above onto one of the first newsprint prints - Serena had a novel way of 'cheats registering' by cutting 4 triangles on the back of the print in key positions so we could position it accurately on the stone (see below)
The cut triangles were unnoticable when the stone was printed due to the pressure exerted from the press.





The first print on newsprint registered quite well using this method but the ink was a bit grey still. Added more velvet noir and burnt umber litho ink to warm it up a bit .  Printed onto both kitchen paper and newsprint prints. More accurate registration was achieved with prints on newsprint as I didn't have to dampen it (so potentially no shrinkage) I largely used the acetate template to register which seemed to work quite well.

Printed on top of some of the watercolour paper prints from the first stone -however it was much more difficult to get tight registration on these ... !!
Heres one of the more successfully registered prints 


                                    


The stone was closed by dusting ink with French Chalk - then rolling over with Non Drying Black Ink , French Chalking again and then a thin layer of Gum Arabic solution was placed.
