Hi!

This is more an idea for a feature upgrade, rather than a question:

I need to make a profile for a printable DVD. The problem is printing a square printer target image onto a round DVD, that strangely enough even has a hole in the middle... If I scale it down to fit it somewhere on the rim, it gets far too small and color patches bleed one into another.

Just a though: is there a way (or will Wink) to add a special round-with-a-hole-in-the-middle printer target image, especially for profiling printable CDs/DVDs?

BTW, great program.

Regards,
Arsen

Arsen,
I have never used printable CDs, but I/we, wife and I do many DVD and CDs using a dedicated software called ShureThing.
This application coupled with purchasing CD printable labels, large center hole or small one, works perfectly.

Hi, Fred!

It is not a problem to print the existing image somewhere on a CD/DVD - I use a utility I got with my printer. But the problem is that the existing rectangle color pattern is not suitable for printing on a CD/DVD, in order to be scanned back and used for profiling, because:
  • If you stretch it to fit the circle, you will be missing the patches in the middle, due to the CD hole
  • If you shrink it to fit somewhere in the rim, so all the color patches would be visible - they get too small.

Hence, there should be a round pattern that would print the color patches all around the rim.

An interesting concept; profiling the actual printable CD as if it was printing paper.
I had never even thought of something like that until now.
I thought you were having trouble getting a round image to print for you.

The only thought that comes to me is perhaps, the printable CD manufacturer or distributor offers a pack of a few sheets of the material that is affixed to the CD or that is embedded in the CD for printing.
Then you could print your target on that material and profile it.

Best,
Fred

Arsen-

Stay away from paper labels on your CD/DVDs.  They are a death threat to your drive and can substantially shorten its life.  Back in the day of 2x/4x (CD) they were okay but not at today's rotational speeds.

There is a huge difference between "printable media" I am talking about, and paper stickers designed to slowly decay your CDs. Abandoned those years ago.

I for one would be all for having a new target for CDs/DVDs..... I've tried using the regular PP target, chopping it up to small pieces and printing on multiple CDs.. it works, but it's a very long process and wastes a TON of discs to get decent results.

It would be nice just being able to print a target directly to the CD, scan it in with the IT8 and generate a profile. Even if it's not as precise as a paper profile, just getting something in the ballpark would be a cool addition. (fewer patches for CDs maybe?)

I'm guessing that getting a good scan could prove difficult however, since the disc is round, it would have to placed in the right direction. PP might need some code to rotate the image on the CD.

To the original poster, if you really can't wait. I know colorvision's Spyder3print comes with CD profiles, but it's expensive!
Some ebay sellers offer CD/DVD profiles (search for them). I haven't tried any of those services/products myself.

As to using printable labels, also see the discussion athttp://ddisoftware.com/tech/articles/october-2009-pigment-vs-dye-today/15/

I know this is an old topic, but the subject applies so I didn't want to start a new topic......

After seeing how popular Profile Prism is over at the Inkjet Printer Forum, I'm considering buying it. The goal is to match my printouts between HP Brochure Paper (glossy) and Taiyo-Yuden (now JVC) WaterShield (glossy) DVD discs using a Canon iP4500 printer.

As mentioned by the OP, the concern is being able to profile the DVD disc. Will I be able to create a good printer profile for these discs?

I have multiple projects a year and waste ~5 discs on each trying to get the colors on the disc to match the brochure paper as close as possible. But it's never quite right so I just live with it. I want to take them to the next level and get them closer while eliminating the waste hence my interest in this software.

Some CD/DVD labels like CD Stomper Matte labels are plain white with no printed areas outlining the punchouts.  On ones like those, you could easily print something like a 5x7 target and let it print right over the perforations and the perforations wouldn't interfere significantly.  If you have other labels that have gray print on them outlining the edge of the CD, the center punch, etc. obviously you can't print over those and there's really no way to profile that type of CD or DVD label because there isn't enough contiguous "virgin" white space available to print the target.  I guess even then, you could get clever if you were desperate enough Smiley and take a couple sheets, cut out some fitting white areas, and piece them together carefully, attaching them contiguously to a plain sheet of paper to create enough plain white label area to print a target on it.  If you don't have gaps, that might even work.

But in the end, if you are really interested in getting a profile for CD/DVD labels, I'd just find a package of labels that doesn't have template designs printed over the label areas: ones that look like a plain sheet of white paper from a distance.  Then just print the target on that and profile.  The CD Stomper Matte White CD Labels (SKU 72782 98102) that I bought at Staples have a plain white surface, but hopefully there are other options because honestly, those are horrible as they seem designed to impart maximum difficulty when actually applying them to the disks (very low quality perforations and no thought put into easy peeling).

Mike

Mike,

The real problem is concerned with profiling printable cd/dvd disks, (The ones with a plain white inkjet ready surface on the cd) not profiling paper labels for sticking on the discs (although that did come up). I think you'd need a circular target (with a  big hole in the middle) for that  Wink .

Best wishes,

Ray

Honestly, I wouldn't bother fooling with those.  Those print so poorly that I don't think they could be profiled even if you could print a target on them.  I've never really understood why people try to print directly on discs anyway.  The printable discs cost more than a regular disc plus a label, the labels are easier to make, faster to apply, and look a whole lot better.

Hey guys,
I am curious about something.

My neighbors have well over 3000 DVDs in the house with movies all labeled and all in professional looking DVD cases like you buy in the store.
I print the case covers and the DVD labels for him.
I use the Let Printer Manage the color, and driver set to ICM...... for all the case covers which are 7.50 high by 10.50 long.
I make the DVD disk labels by buying good quality labels from a company called NEATO.
If I buy good quality labels, then Let Printer manage color would work fine.
I use a program called Shure thing. This is so accurate (placement) to the millimeter and can be adjusted .01 mm at a time to get it really centered....
All that is a preamble.... BTW the R1800 will print on the printable DVD blanks.

Where do I get the images from?
Where do I get round disk labels from?
 
I get them from 2 sites for free.
Where did they get them from?
Uploaded by many people all over the world from scans of what they bought, or some are custom designed which is another hobby people have.
The scan colors and the scan quality vary from person to person and scan to scan.
In other words, if I ask for cover and disk images for a movie, "The King's Speech", I will have probably a dozen choices sent in by a dozen different people. That is only region 1!
So I ask you, how fussy are you going to be with profiling a hard printable disk, or trying to make a round target with a hole in the middle when your source material is, at best, subject to scrutiny?

I don't mean to be picky, but ..... real life is real life!!

I suppose there is no chance of profiling the 'lightscribe' cd's, then Cheesy
