Title: repair canvas before coating?
Post by: mstevensphoto on March 01, 2012, 12:44:17 pm
Hi all,
   I've got a very large canvas from my ipf8300 that represents about $90 in ink and at least that much again in canvas - it looks like it caught a folded over edge or something and there's a scratch in the ink in a totally black area of the print. Given the cost of the materials I'm wondering if there is a way to salvage this before I spray it with varnish (or after for that matter). I've used oil paint pens to fix dinged corners, but it's always an approximation and it works only because it's on the corner so one doesn't really see it anyway.  the scratch does not go all the way through to the white of the canvas, it kind of looks like about a 4" blonde hair on it...I'd love any suggestions of materials/techniques for the fix.

If you have any old ink cartridges you can use a very small paint brush and dab some ink on it then paint in the black area.  I've done this many times in the past on totally black areas.

You're lucky it happened on black and can easily touch it up!

Black is easy,Sharpie. I try and blend it in with a dab of the finger.
If you have a left over cart of mk or pk whichever ink you used.
Open it up and put a little of the matching ink on your scratch to blend in.
The Sharpie is just too easy.

break out your 'empty' black ink cartridges and a 00 brush.  ;D

pure black areas are the easiest to repair.

Sharpie can't be good for archival purposes.

Sharpie will fade in a matter of days. Not good.

(Sorry Dan) :)

These pigmented markers are supposed to be good at canvas touch-ups...

Done more then a few with a sharpie and never have seen any fading issues.
Most of these repairs are at corners where all it needs is a little bit of black color to cover a little nick.
Also a little dab of glamor II helps blend the the blacks.
I use the Faber markers as mentioned above,but they do not have a black.

Ken,
Archival,are you serious? We are talking dabbing a little black ink on a damaged corner of a family dog picture. :)

Dan, we're not talking about dabbing a Sharpie on corners.  The OP clearly stated the scratch was on the surface of the print.  Big difference.

How do you know Sharpie's don't damage your prints over time?  How many of your prints have you seen that you printed years ago?  Once canvases leave your hand, chances are you are never going to see them again.

Plus, I have first hand experience with a sharpie on canvas.  Many years ago my son had a canvas autographed by Curtis Joseph (former NHL goalie).  He whipped out his Sharpie he was using to sign everything else and before I got the chance to pull out my marker with pigment ink the autograph was done.  Looked fine for a bit until it faded and faded out the ink immediately surrounding his signature.

Yo Dan, I'm really not trying to get on your case today  ;D, but I have a Faber-Castell PITT artist pen that has black ink, which I use to sign my prints. It is part number PP 4 005401 673996. The barrell says it is 'Indian ink - waterproof - maximum light-fastness'. Just sayin'...

These are pigment pens normally used to sign prints. 
The ink is really black, it's archival and they have a variety of nibs.
Might be worth a try

You don't need an old cartridge (though its not a bad idea I keep mine) you can just pull out your current cartridge use it and put it back in.

thanks for the suggestions. Sharpies are loaded with acid I wouldn't consider one. I've seen them create an ugly yellow/orange halo in a very short time. I'll see if I can get some black out of my cartridge, my main concern on the markers is sheen, everything I have seems to be too shiny compared to the rest of the image. wonder where my good paint brushes are.....

Randy,
My Faber 5 ink set did not have black.
Look for a call from me to order one for future surface repair. :)

Ken,
Sorry I read the scratch in the folded over edge to mean edge damage not the surface,my bad.
I was talking corner repair all along.

Gotcha, Dan.  I didn't think you would use a Sharpie on the surface of a print, but you had me worried there for a bit ;)

I have the 48 pen box set by this manufacturer and it has been AWESOME for touching up minor issues. It doesn't change once Glamour 2 is applied and appears stable. The box states that the inks are non-fading. I've lost count of the number of larger canvas prints I've saved with these.

I always use my 6x eye loupe when applying. These pens reward a very light touch.

…one of these days I have got to get the belt replaced on my Z3100 ::)

   Ken,
 It sounds like the canvas is huge and I guarantee that nobody but you who has been pixel peeping at it with a magnifying glass, would ever notice it ;) You already have most likely become overly concious of it and your eye keeps subliminally being drawn to the imperfection.

    I strive for perfection also in my framing business, and in all the years and all the imperfections I have noticed I have discovered that people DONT notice the things I do.!
 Use the ink touch up technique , coat the canvas as always , and force youself to believe you never saw it in the first place. it will  then magically vanish from view. ;D

David 

You mean Mark ;)

You're right though, I notice the imperfections that others would never, ever find.  Not sure about the OP, or anyone else, but because I am a perfectionist and I notice it, I will almost always just re-print now.  However, on a canvas the size the OP mentioned, I would use the advice I gave earlier and get a small brush and dab some ink on, then coat as usual.

I picked up the Faber-Castell Pitt pens (48) a week ago and used them for the first time this morning to cover/correct a small blemish on a corner.  The area was black and using the black pen I can hardly see or tell where I used it.  I think dark colors will hide/blend easier than say a sky so time will tell however so far I'm very pleased.

I dug into the colors a little more and found with a little research I can match the RGB values.  Going to make a chart soon then on a image that needs attention I'll bring the file up to check the RGB then hopefully choose the correct pen.  Yeah anal is my middle name... :D

We use acrylic paints for retouching any color, mix the color on a palatte
spray first.
if you need a glossy retouch they make gloss enhancers for mixing w arylics.

dot dot dot , smaller dots are better
dont brush it on like an artist

thanks for all of the suggestions. for those who care:

showed the print to my girlfriend and said "do you think this looks ok" she immediately said" is there something on it down there?" - damnit, that meant a fix was for sure necessary.
dug into an okd MBK cartridge and oh so carefully traced over the spot, then accidentally smudged it, then like an idiot tried to cover up an ink mess with more ink BUT in the end I used my finger to lightly blot/retouch the area, not unlike I used to do when drawing with charcoal. By that point I had a 3.5" long, finger width area that no longer showed the scratch but had an obviously different sheen. I then decided what the heck I'm in it for the education now and who knows so I sprayed it. Of course fate hates me so I got a big black dog hair right on the subject's face in the varnish BUT the one good thing about digging around in wet varnish to remove a hair is that more varnish actually does help. End result, thicker coat than I would have applied otherwise BUT there is no visible change in the sheen where my repair was and in fact no visible anything, so ultimately success!
thanks to all of you!
Mark

I'm laughing WITH you.  I love a tale that is funny, well-told, and has a good ending.  I'm glad everything worked out.   :)

P.s.  Thanks to kdphotography who supplied the link for archival felt pens.  I bought some!

For serious touch-ups we print just the part that was damaged and an inch or so around, on a non absorbent acrylic sheet using the front load on the Canon 6100.  This gives you a nice pool of the exact color.  Yes, fine dots are a better application technique than brushing on.

I've been down this road where the more I try the more it gets worse   - even doing the 'print the same area on some plastic' trick - only when you have mixed colours where a touchup isn't noticeable or black you usually have a chance - blue skies - forget it - unless it's a tiny spot - then maybe. Generally I give up fairly quickly - it's easier making another print (time is money). Still hurts seeing a ruined print-  like getting wads of cash and burning it...
