No. 40, Scanner Trouble, Part 2: My Solution

If you recall, I had complained here about the fact that my upgrade to Mac OS 10.8, known as Mountain Lion, had rendered my Mustek large format scanner useless: no drivers available!

My scanner was, in the words of another online complainant, no better than a doorstop--a dead weight.

My goal was to try to find a fix for this other than replacing the scanner itself.

First, of course, I tried software.  Nothing worked, including VueScan, where I actually talked to the owner, who said that scanner drivers are notoriously badly written.  Mustek's website said to go to Apple and get a driver from them, but there was nothing there.

Then I thought: what if I could get an old Mac that was still running on an earlier operating system, and dedicate it to the scanner?  And that is what I did.  The scanner is now paired with an iMac running Snow Leopard.  I did still have to download a driver for that, but it worked.

The Mountain Lion is tamed!

Now I am happily back in business!

A special thanks to David Nethery, who posted a comment just a few days ago suggesting both Vue Scan, which he didn't know I had tried, and the fact that Brother makes a couple of scanners that might have done the job for me, had I found it necessary to replace the Mustek.

Mountain Lion Can Be Dangerous!

I am a long-time Mac user, and I felt I had gone too long without upgrading my operating system.  Last month I was still on plain Leopard, which was three upgrades behind.  Software was beginning to appear on the market that would not run on Leopard, so I had to first move up to Snow Leopard before I could move on to anything else.  But then I was able to leap over Lion to the current system, Mountain Lion.  Up to date once again, I could breathe a sigh of relief, until...

Until I attempted to scan a drawing.  First it crashed Photoshop, repeatedly.  Photoshop CS4 is what I have always used to import images from my scanner, a Mustek large-format flatbedl, the model A3 USB 1200 Pro.  I recently wrote glowingly about this scanner in my post Drawings Into Digital: Part 1--Scanning.  That was in early November of last year.

A paperless drawing.  Yes, I can do them, but I still want my scanner back!

Now I am out on a limb.  It turns out that Mustek does not have drivers for their scanners which work on OS 10.7 (Lion) or 10.8 (Mountain Lion).  For me, this is bad news.  My Epson Stylus CX5000 all-in-one (scanner, printer, copier) also will not work in scanning mode, but I could replace it for about US$80.  I can't replace my Mustek large format scanner so easily, and it is very important to my work.  As an animator who works on standard animation paper, which is 10 1/2" x 12 1/2", I have to have a large format scanner to get my hundreds--sometimes thousands--of drawings into the computer efficiently and in correct register.

My hope is that Mustek will soon provide the needed drivers, and I will be back in business.  My hope is that it is fair to say that they do not yet have the drivers--but that they soon will.

Anyway, for now I hope other Mac users who depend on their scanners will be alerted to this problem.  I will be posting some warnings on Linked In animation group sites also.

Paper To Digital: Getting Started

Having cleaned up all drawings for this scene in black pencil, next I scanned them into the computer for "ink and paint", the old expression for getting the drawings into final line and color form on a transparent field, just as in pre computer days they were actually inked onto acetate celluloid, their colors painted in on the back of the cel.  I have actually done this, and as an independent animator I mean that I--not some employee or underling--have actually done it.  Mixing paints, doing test cels to get the right colors, doing let-downs (compensating for the gray density of each cel by lightening the paint colors incrementally, so that the parts of one character on multiple cel levels would all appear to the camera to be the same color and value), waiting for the paint to dry, repairing damaged cels where the paint turned out not to be dry, and so on.

All that is in the past, and I am glad to embrace what computer animation can do in this area.

First step is scanning, and I recommend the ScanExpress A3USB 1200 Pro Scanner by Mustek.  It costs under US$200 and scans up to 11.7" x 16.5" (29.7cm x 41.9cm).  I learned about this scanner from a comic book artist friend and was excited, because all scanners I knew about  that scanned any larger than American legal size (8 1/2" x 14") were priced in thousands of dollars.

The Mustek ScanExpress 1200

This scanner works in a wide variety of resolutions and scanning modes, and it can batch-scan 10 copies at a time. I access it through Photoshop, where the scans appear in a stack.   For mode I choose Grey.  In this way I get all the shadings of the pencil drawing, which I like to see when inking over them digitally.  But it is possible to also scan in color, at either 16, 24 or 48 bit.  Color scans of animation drawings may be useful when colored pencils have been used to code such things as match lines or  tracebacks,  or to indicate a particular inking color.

When scanning pencil animation drawings, registration is of course critical.  Unregistered drawings can be troublesome and time-consuming to correct.  And it is important to know that acme or other registration holes are not always consistent in their relationship with the edges and corners of the paper in which they are punched.  Therefore, even the most careful alignment of drawings into the corners and edges of the scanner bed will not assure registration.  The three registration holes may vary in their location from sheet to sheet by as much as 1/8" (.3cm) from the edge; moreover, they may be skewed--not level with the edge.  These variations are unacceptable and can ruin your animation or cause you much grief in their correction.

Toon Boom Animate Pro, as well as some other animation apps like Toonz, offer a peg hole detection feature, which automatically aligns your scans by their peg holes.  But to use this feature, one must scan in the Lineart mode, which produces an over-simplified rendering of the pencil drawing that I do not favor, all black or white with no values inbetween.  It also has low tolerance for any enlarged or irregular holes and can fail as often as not, in my experience.  In any case, as I prefer to see the bitmap nuances of the pencil drawings, this does not work for me.

Perhaps a better option is to equip your scanner with a pegbar.

A standard thin metal acme pegbar taped to frame of the sccanner bed, just outside the scanning field.

This will work very well for registration if 1) the specified scanning field is exactly consistent throughout the entire scene being scanned, and 2) the pegbar is taped down securely enough that it does not drift or shift its position in any way.

The Mustek scanner actually appears to have been engineered with this possibility in mind, as the inside surface of the scanner cover includes a slot all along its right side that will accomodate the acme pegs that project up from the pegbar.

Here an animation drawing has been placed face-down on the pegs of the scanner.

For this scene I scanned all the drawiings at 150dpi.  Even this rather high resolution does not show absolutely all the pencil detail once the drawings are imported into Animate Pro, so on certain critical scenes I will probably choose a resolution of 300dpi.  I would say that 72 or 96dpi would tend to be inadequate at any tiime.
