Lineco Neutral pH Adhesive PVA for Gum Printing

[donbga]

Has anyone used this for sizing paper in preparation for gum printing?

Thanks,

Don Bryant

Hi Don

My first post on gum and I am a newbie on this , but over the weekend we used Gambin Polyvinyl Acetate Sizing and dilute PVA 1 part plus 2 parts water on Fabriano Artistco paper.

Not large prints approx 8x10 on 11x14 sheet, I witnessed over 40 registrations with multiple layers and no sign of mis registration due to shrinkage and the gum did stay on the paper well.

Don your gums you showed me are stellar, I now want to see a 16 x20 come out of your darkroom.
Love the process but the method we saw and used involves more brush work than I would ever want to use, but some of the people made pretty shit hot gums for their first attempt.

Christina Anderson is a wonderful teacher, and a good person to boot.

Hi Bob,

Glad to hear that your workshop went well. I've heard that the Gamblin works pretty well but I'm sure Ron Reeder uses Lineco 1:1 and I've got a one on one palladium printing workshop coming up in December and the person I'm teaching asked about using Lineco for gum overs. We will probably end up testing both in her darkroom.

I'm glad to hear that your workshop experience with Chris was very positive. Chris is a dedicated teacher and probably doesn't receive the recognition she deserves in some quarters of the alt. printing community.

Her energy level is tremendous; she lives her life on roller skates teaching at the universtiy level, producing her own work, writing books, giving workshops, serving on SPE committes.

So I can hardily reccommend to anyone needing a workshop on tri-color gum printing or just gum printing that Chris is one of the tops.

Project Basho has lined up an impressive group of instructors for alternative processes, it's a great place to come and learn.

Thanks for the comp. on my prints, I'm working on the other project. More info when I can, but first the House of Atriedes must be put in order.

Don, Just to clarify, I have never compared Gamblin PVA glue with the Lineco stuff. Dan Smith carries Lineco and it worked pretty well the first time and I never tried anything else. I would be curious to know if there is any significant difference between the two products.

Cheers, Ron Reeder

First, Gamblin isn't a glue (as it comes in the bottle), it's a size. It's very watery compared to the Lineco PVA glue.

I use the size (occasionally) for gum printing and the Lineco as a bookbinding adhesive. Both are great products for their intended uses.

As many of you know, I very rarely size for gum printing, having found Fabriano soft press to have clear whites and no staining with my method.

Hi Paul,

You are correct the Lineco product is a pH neutral adhesive, though some people are using it to size with diluted 1:1. It comes in a plastic bottle like Gamblin but is quite a bit thicker. I was just curious if anyone had any usage notes to share.

I'm not a big fan of the Gamblin size because it leaves a visible sheen though perhaps not as much as the Lineco product. In a workshop environment these products may be more desirable since they allow a wider selection of papers and can be dried quickly with a hand held hair dryer.

I still prefer a hardened gelatin size, which when applied properly is quite transparent and not nearly as reflective as the PVA sizes.

Why do you think the Fabriano soft press is reticent to stain? I'm assuming there has to be something about that paper that inhibits gum staining.

Don, I think it has more surface size on it, or at least the batches I've ordered have.

I don't have a problem with Fab HP either, but the SP seems even moreso.

Paul-- When I asked the guy at Dan Smith about Gamblin size he maintained it was just diluted PVA glue and sold me a bottle of Lineco, the undiluted stuff. What do I know? Anyway, diluted Lineco works for me, keeping the highlights from staining (on Arches Platine paper) when I do gum over palladium prints.

And Don, as to surface sheen, all the sheen I get seems to come from the gum rather than the diluted Lineco.

Cheers to all, Ron Reeder

FWIW, this tech note is listed on Jerry's Art-O-Rama as part of the product description of the Gamblin PVA. So it seems that the Lineco maybe an economical alternative as the person at Daniel Smith. Which makes think that other similar products could be substituted. Thanks Ron. Using the Gamblin as demonstrated by Jeremy Moore on youtube does make sense:

TO BE USED AS A SIZING ONLY. THIS PRODUCT IS A
WATERED DOWN VERSION OF THE NORMAL PVA GLUE SO
IT CANNOT BE USED AS AN ADHESIVE.

FYI, FWIW, I use a clear*, water-based (PVAc*), waterproof* paper / wood glue as sizing, diluting it 1+3 or 1+4... No sheen (or negligible sheen - if any) and perfect results. Search for products with the keywords marked with (*) and try them. I bet you'll find a suitable product within the first few tries.

Loris.
