Special effects

I am just wondering what people have done on work with varnishes. I am looking to create some visual effects with both gloss and satin, I have seen one go down and then dry traped onto anouther to create a pop-out effect. Or was it coating down then dry traping varnish. I am running a 40" offset w/coater. Anyone know what im talking about?

 

Here is what works best!
-Gloss paper
-Matte or dull varnish
-Gloss Aq.

Apply matte varnish on everything you want dulled back, then flood gloss aqueous on top, in-line.

This effect works better on darker colors, lighter colors, you will not see as much contrast.

For added effect, you can add 3% opaque white or silver to the matte varnish to help "frost" back the dull portion of the piece to create a different style of contrast.

Edit to add, make sure you run a heavy ink film of matte varnish when running, it will enhance it that much more.

Hope this helps!

 

I run special matt etch varnish over a gloss celloglaze sheet, it looks like a spot uv for a fraction of the price.

 

Thanks! that's exactly what I was looking for. I saw it done back in the early 90's but couldn't quite remember what the pressman did.. I do remember him adding opaque white also..I was really supprised at how nice it made an image stand out. Funny part is i've only seen this done once for an in-house job and now its the same situation. Nice as a selling point, but never see costumers using this. Thanks again!!

 

Your welcome!

Good luck and let us know how it works out for ya!

 

We print our 5 colours then on the 6th unit we run a sealer called underlack sealer - this is printed with a plate with image on it; then Gloss Aqueous on top. The underlack sealer repels the aqueous coating - so you end up with a spot aqueous effect.

 

The "underlack sealer" you are refering to does not "repel" aqueous coating, it diffuses light to maintain a dull look even with the aqueous on top.

 

i have found that when looking to achieve multiple varnish effects and or coating effects it is easier to dull down a gloss stock than it is to gloss up a dull stock. keep that in mind when your planning your job

 

I have a customer that requires the effect that you mention but, they don't want the bookcover to fingerprint. What we have done is print the cover as you normally would then apply a nylon, AGS gloss laminate, then go back to press with a plate knocking out all that you need to gloss and apply "elkote dull varnish". This special varnish is manufactered by Delta Printing Solutions (www.deltaprintingsolutions.com) and it allows you to print directly over the laminate. Go to their website and you will get all the information.
It is a beautiful effect and not difficult to work with.

 

Ive done either Gloss coating followed by matt press varnish OR gloss coating followed by matt polymer on twin coaters.

 

whats a celloglaze sheet?

 

Celloglazing is a process whereby a thin sheet of film is adhered to the printed piece by a special machine that uses both heat and pressure to apply the coating.

Celloglazing can be matt or gloss and can be single sided or double sided. It is a relatively slow process, and is more expensive than machine varnishing. The process tends to add depth to colours, robustness, and produces a rather luxurious, classy, ‘expensive’ look to the product.

 

What are asking about is called A strike thru varnish you run your colors down first then A strike thru varnish then A coating .All in line you dont see the effect as much when it is wet but as It dries I does stand out .Aso it works better meaning looks better on darker backgrounds

It is also called drip-off coating.
