sRGB,Adobe RGB,and Pro Photo
Feb 1, 2015 20:58:49 #
Today I took an Image in Adobe RGB. Tomorrow I will Process it into Pro Photo and then do copies into Adobe RGB and One in sRGB. I will submit these images on this site for your inspection. If anyone is interested what the procedure was I will be glad to accommedate .
Also I will print ALL profiles of this image on a CanonIPF 8400 ,including the one saved as ProPhoto. And ,I swear that what you will see on the site is what will also be printed.
I can't beleive that Professional Print Shops are telling customers that they can only print in sRGB profile. Personally I would stay away from them.Why would there be a Pro Photo that gives you such a wide gamut if it can't be printed.They are full of s--t.

You need to understand these profiles. Each has its own gamut, mainly for monitors. Each printer has it own gamut. Furthermore, the shop may a true rgb photo printer or it may have a cmyk ink jet printer. This whole thing is tricky and you might want to research it further before swearing at anyone.

100% agree. I ran a digital print shop for a while, the printer was only capable of sRGB.
The modern print shops find it unprofitable to change colour space protocols as it slows down mass production and would put prices up.

I'll be interested to see your post. I can print successfully from any of the three color spaces at home on my Epson r3000 because I've taken the time to figure out how, and the printer accommodates that. If i tried to do the same thing on my dinky little Epson 830 all-in-one, I'd not have such predictable results as it lacks the controls of the r3000. I print my own stuff up to the r3000's size limit, but when I send out larger stuff I pay attention to the print company's instructions about color space or I'm likely to have a bad surprise.
And for posting on UHH, a post here in the ProPhoto color space is virtually guaranteed to look bad, and Adobe RGB is unpredictable. Take a look at my first post on UHH when I learned my lesson on that. The first post was in ProPhoto, the only change in the second (later in same thread) was switching it to sRGB which made it look like it did on my monitor. http://www.uglyhedgehog.com/t-119959-1.html

Actually I was makingf a comment,I don't see any swearing.Secondly the gamut is the range of color,most professional printers use rips which gives them thier color ,and CMYK are used basically in Sign Shops ,myself that the last place I would look to having printing done for images.

I'm not to familiar with Epson and don't know if you can get a print module with it. The canon that we use does come with it and we can use that through photoshop so we don't have to use rips.Once the photo has been done from the onset in Pro Photo, we can print in Pro Photo (largest gamut), Adobe RGB ), And in sRGB(smallest gamut)
I;ve found that if you try to process in sRGB or Adobe RCB and try to change to ProPhoto you end up with really weird stuff sometimes.
I wont be able to put anything on the net asfar as images that I took .Left my camera in town and not going in with the storm we're having now.

You are wrong on all three points. The rip does not give the color; the file already has it. One of the things that the rip does is to bring the job into the gamut of that particular printer, inks and medium.
As for the last point, if I want prints just for viewing, I have them printed on a Noritsu for cost and convenience. If I want canvas or am mounting a large or panoramic print, I print on a 63" solvent printer like the kind used in photo labs, print shops and sign shops. When viewed at the proper distance, one cannot distinguish the quality between the photographic and solvent prints. Just like anything else, the quality depends more upon the operator rather the shingle over the front door.

Some people might view "They are full of s--t." as swearing.

Thank you for correcting me on the first part (RIP) As far as the second part of your reply I really beg to differ.I have had Prints done of Painting taken with a digital back and then had some printed at a print shop .Ran out and had to drive 300 klicks to have some more done .Was in a hurry and didn't have a printer at that time large enough.Went to a sign shop,showed the proprieter the CD that the original printer had given me and told him what I wanted,also left a print from the original set with him to have for reference. "this printer came highly recommended" I had and still see a lot of his signs around,and they look very good,but that's what they are .Signs. The rendition that he produced were off by about 2 tones,the contrast was terrible. I paid him and never used the prints.

A long time ago I had an Epson 7500 (I think that was the model) and this was set up for printing CMYK proofs prior to being commercially printed. That same printer was also popular in sign printing establishments but the profiles were very different. The contrast, brightness, black and white points were set very differently for the two applications.
The same image, printed out on a sign writers 7500 and a repro house's 7500 would produce very different results.

First of all, if consistency was of such importance, then you should have used the original source. As for the sign shop, if that were my business, I would have cautioned you that the prints would probably vary due to machines, inks, profiles and substrate, I would have asked why you were not going back to the original vendor and how much variation would be acceptable. I might have turned down the job at that point. However, if I did accept the job and the results were off, then I would have let you decide if you wanted the prints or not or wanted them redone. It is as simple as that.
Because you had a bad experience with one sign shop, you have decided all sign shops are incapable of doing what you want. I do not know what your expectations were or even the specs of the job. Regardless, to brand all sign shops as unsatisfactory is simply wrong. In my business, we have a saying: the customer is not always right but he is always the customer.

Come on Searcher, do you really believe that? Why do you think that is so?
