VIRKOTYPE Raised Print Compound

Sprinkle it on wet ink. Dust off the excess and put under heat to raise. A hair dryer on high or a toaster oven has been mentioned as possible alternatives to the real thing. There are a couple on ebay if you want to spend the money and have the room.

it is a thermographic powder put on wet ink and then heated to give a raised image.

Thanks Folks,

What temperature range do you think would be appropriate and for what period of time?

The temperature is usually hot enough that if you leave the sheet in the heat for more than three seconds it will scorch ,five to eight seconds and it will ignite . a good method is to dust ten prints and run over the appropriate area with a hot air gun (the type used to strip paint) dont use a blow torch. Some of the types of powder sold in card hobby shops work at lower temperatures and can be made to flow with a hair dryer ,however it is to be noted that these powders are not suited for use on anything that is going to be put through printers that use fusing to dry the inkor to fuse the inks that they are applying such as a digital printer would use .

Little addition to Peters, as above several methods have been tried, many with good results as a quick fix, for a one off! For semi mass production the answer is a thermograph machine, in essence a chain link belt, driven under the battery of heaters at infinately variable speed, according the stock and surface area of image etc. It has been adequately demonstrated to Me that the operation, (up to a point) is an acquired knack, in view of the stock used and, now in view of porous paper, card, hand made dampened etc, exiting the machine nicely raised but warped and negotiable? Here we see H/berg platens and similar streaming straight into thermo machines but unfortunately governed for speed, by the pace of the thermo machine, but still beautiful results especially in more than one colour!!! In our transport cafe,s or road houses, where they usually have a trucker friendly, freebie, notice board, when there is only, even one or two, thermo business cards on sight, they stand out literally and metaphorically with the house light picking them out. Of course “Young Ladies Seeking Part Time Work” do sneak one in occasionally, but the Management do keep an eye open? So I have been told!!

See ,he is indeed a smutty old bot belch !!
Thermo has kind of fallen by the wayside in recent years so the ladies of ill virtue used to get mick to dust them for them
!! And the cards.
letterpress was always the best way to place thermo powder as the ink layer being thicker stayed sticky for longer ,the advent of the litho and thinner ink film made it a royal pain ,continuously stopping every twentyfive sheets to dip and feed them into the tunnel took so long theplates on the offset would dry out and when you started up again to run your next block the machine would catch up (the non image areas of the plate would pick up ink ),so you would flash up more water and then the ink would not sit on the image area of the plate and the colours would become wishy washy and weak., having done runs in excess of fourty thousand letterheads this way i assure you its a proper pain .
