Trouble with Peg-Hole Registration

[LivieLightyear]

Hi there! I was just wondering if anyone else had a problem with the Peg-Hole Registration feature. Whenever I try to use it, it very rarely works. Most of the time, it actually makes it worse. Am I doing something wrong? I set the "red boxes" the same size as the peg-holes and in the same place as the original holes are in the first frame. I click "Apply" and instead of lining them all up, the drawings are all over the place. Some even get changed in size and angle, and they all look blurry. I must be doing something wrong, because sometimes it works great.

Any tips or tricks?

did you try to set the red boxes a lot wider?
I'm not sure but i think the red boxes are meant to set the general area where the holes in your scanned sequence approximately are. So setting them can be done quite roughly.

That's true : the red boxes must be a little wider, because if your pegs holes of the next sheet are not in the red boxes, those pegs won't be re-aligned.

Don't forget if one peg is really too far from the original red boxes, the peg registration may fail. =)

the same size as the peg-holes

wrong way to do it , all PEGS holes from all frames have to be in a red box.

I found in testing this feature that it is best to place the drawings on the scanner bed as accurately as possible to begin with , so if you are scanning off the peg bar with a flatbed scanner you should try to place each piece of paper on the same place on the scanner platen (using the L -shaped corner edges of the scanner to align each drawing as closely as possible in the same place) . This will still result in the scanned drawings being fairly close together , but still too "jittery" for the necessary accuracy of registration , which is why we are using the Peg Hole Registration to begin with. Even being careful with the placement the scanning off pegs is still much faster than placing each drawing on the peg bar, then taking each drawing off the peg bar for each scan.

Where the Peg Hole Registration will fail is if the drawings are placed on the scanner haphazardly so the peg hole positions are jumping around erratically, an inch or more apart . That situation makes it difficult for the Peg Hole Registration to accurately line up the peg holes. I tested it to see how far I could push it until it would not accurately line up the holes . I found that as long as the peg holes positions are not too far apart from drawing to drawing then it works very well. Again, the whole point is to speed up the process of scanning so when using a flatbed scanner we don't have to place each drawing on the pegs, then take each drawing off the pegs over and over ... However, it is not hard to place the drawings more or less in the same place each time on the scanner platen using the edge of the paper lined up with the L-shaped edge of the scanner.

The other option is running the drawings through a scanner with an Auto-Document Feeder , which will keep the drawings in fairly close registration , but with enough jitter that the Peg Hole Registration must be used to nail down the proper registration.

The other very important thing is that the peg hole shapes be scanned clearly outlined as SOLID BLACK shapes. This is done by placing a strip of black paper along the top of the scanner lid where it comes down and covers the peg holes (so when scanned the peg holes are backed by solid black) . Or just leave the scanner lid open , in which case the peg holes will be scanned as solid black shapes. (although by leaving the lid open you may sacrifice a bit of accuracy in that the lid of the scanner is not pressing each drawing flat to the surface of the scanner glass ... if your paper is buckled a bit from constant flipping then you may get a bit of fluctuation . This is acceptable for ROUGH tests, but for scanning final drawings it is best to close the scanner lid on each drawing to press it flat against the glass.)

For the Auto-Document Feed scanner put a strip of black electrical tape along the path of the paper where the peg holes are pulled through . This will ensure that the peg hole shapes are scanned as solid black shapes.
