My stand-in at the shop took in an order the other day that included a blueprint drawing on some sturdy modern paper vellum.

I just searched out forum here to confirm my suspicions -- due the plastic nature of this "paper", we do NOT want to drymount this in our heat press. (But said helper apparently was going to do so, according to the work ticket).

Its 24x36, and scheduled to be put in a Swiss Clip frame. The paper has heavy creases in it, but otherwise lays flat.

So, what's the best way to handle this? Probably spray mount, unless I want to invest in someone else's mounting board, or pull out the Yes! paste.
 
If it is sturdy and if it lays flat - why mount it at all? Just stick it in there - gonna get bugs crawling in the edges anyways with or without mounting. ;)
 
Is this a blueprint or a drawing? Those are two different types of media and require vastly different handling.
 
Sometimes when I come across something that I don't want to heat mount, I send it to a local graphics company that does cold mounting and gloss and matt laminating.
I do some work for a company that just wants their posters mounted on Gator board and laminated and hung without frames.
This local graphics company has the equipment and ability to mount on Gator, Sintex(not sure I spelled it right), or just about any type of mounting board. Sometimes I prefer to outsource. :kaffeetrinker_2:
 
Definitely DO NOT use spraymount or Yes paste. This type of paper does not "enjoy" being mounted.
I would suggest laying on a piece of foam board and use a self adhesive acid free tape strips along the edges, as if you were hinging.
Swiss clip frames-I would trash those-unsafe!!!
 
Dave, you caught me. It is an architectural drawing, not a true blueprint (as done of photosensitve paper). I'm mostly inclined to not mount at all, and just let the pressure from the glass hold it in place.

As far as selling Swiss Clips and Uniframes: Yeah, I'd rather not sell them either. However, I have to have something for customers that come into a custom frame shop and don't want to buy a frame. I just recently quoted a job using Swiss Clips on a 60-inch wide print. Don't think it will go through, by the time I was quoting gatorboard, jumbo size mats, and acrylic, the guy couldn't leave my store fast enough.
 
Since it's going in a Swiss clips contraption anyway, I'd vote for no mounting. That 'vellum' paper is tricky stuff, and different sheets from different manufacturers react differently. Whatever you do, don't let any moisture near it (well, micro-dots of very stiff wheat paste are ok if you really need to hinge it). Don't even breathe on it heavily. Unfortunately, I know this from experience.
 
If this is truly an architectural drawing on translucent 100% rag vellum... such as Clearprint 1000H, which is the most common drafting vellum... then you could dry mount it without any problems. If using dry mount tissue be sure to use the white tissue made specially for translucent materials.

You also could possibly use Kool Tack or SpeedMount but I have never done it before and don't know for sure what results you'd get.

If it is a plasticized paper, which rag vellum is not but there are some synthetic drafting papers that are plastic on the market... then I wouldn't attempt a dry mount without experimenting first.

If you are not familiar with the rag vellums and plastic papers then ... and I'm hesitant to tell you this... the paper will tear whereas the plasticized paper will not... this is one way to test to see which you have.
 
In our scrapbooking part of the store we sell a special tape made specific for vellum, it is made by 3L. If you need more info let me know
