Hello;
I am looking for instructions on how a digital photo should be presented when getting it printed on canvas. My work seems to look fine on my computer, and the pixel size (as much as I know) is correct for the enlargement size. However when I send it in to the printing company, most of the time it comes back too flat, too light, and not as sharp as I thought it should be. Then when I make the PP'ing more contrasty, darker and the file bigger, it comes back TOO dark, and/or TOO contrasty, AND the image doesn't seem to be any sharper?
I have been told that the correct way is to invest in screen calibrating equipment, and work with the printing company on getting my and their parameters alike. Right now I can't afford to buy any more equipment. I just need to know how I can get some more consistent results.. Thanks.

The simple answer is that without a calibrated monitor and the lab's printing profile installed in your operating system so you can use it as a proofing profile, you WILL NOT get consistent results.
Monitor calibration kits start around $100 and will SAVE you a lot more than that over time in wasted lab bills, wasted materials, and disappointments. It IS possible to have what-you-see-is-what-you-get color on your monitor! It takes time, self-education, patience, and understanding to get there, but it is worth it.
I have a calibrated iMac. I use a Spyder5Pro kit to calibrate it before each important editing session. I use Epson printers with their paper profiles installed in my system. I proof with Lightroom or Photoshop, and the paper profile used as the proofing profile. When I send out for lab prints, I use the lab's profile for the paper I'm ordering. My prints are predictable!
Things to ask yourself, based on the five years I ran the color correction department of a pro lab:
• Are you working in a VERY dimly lit room, with absolutely NO glare onto your monitor? (a single 9-watt, 5000°K CFL, bounced off the ceiling behind the monitor, is about right!)
• Is your computer operating system desktop medium to dark gray? (NO bright colors or background images)
• Are the desks, chairs, walls, and floor of the area chosen for medium neutral gray tones? (Munsell N8 paint is expensive, but completely neutral...) (In reality, most of us settle for an area without glaring colored objects or furnishings. Do not wear brightly colored shirts while adjusting color.)
• Are you using a hardware and software calibration kit for your monitor? (It is IMPOSSIBLE to calibrate and profile a monitor correctly, without a colorimeter or spectrophotometer and software solution!)
• Is the monitor black point set to about 0.5 cd/m^2 (candelas per square meter)?
• Is the monitor white point set between 80 to 120 cd/m^2? (We used 105 cd/m^2 in the lab.) (THIS WILL SEEM DIM.)
• Is the monitor color temperature between 5800°K and 6500°K? (Follow your calibration kit's recommendation)
• Is the monitor profile installed in your operating system?
• Are your (and your lab's) printer/paper combination profiles installed in your operating system? (You would normally use a UNIQUE profile for every combination of printer and paper in use.)
• Have you enabled color management PROPERLY in all your post-processing applications?
• Have you taken steps to ensure that your output is not DOUBLE-profiled? (i.e.; Don't let Photoshop apply a profile, while your printer driver is applying the SAME profile! Manage color from one or the other.)
• Are you viewing prints in an industry standard manner? (5000°K fluorescent light, 91+ CRI, at about the same brightness on the print surface as your monitor?)
• Have you studiously avoided tweaking your monitor FOR ANY REASON after you calibrate and profile it, except to RE-calibrate and RE-profile it?
• Are you lucky enough to have reasonably color-accurate vision? (Avoid excessive caffeine? Avoid lack of sleep? Avoid recent exposure to extremely bright light (daylight)? Avoid adjusting color under stress? Avoid adjusting color if pregnant?
• Are you saving files for your lab in the CORRECT COLOR SPACE? (Most labs default to sRGB, but can use another color space IF YOU TELL THEM WHAT YOU ARE USING. Consult your lab to learn their favorite file formats and ICC color space!)
I'm sure I left out a few tidbits here, but these questions can steer you onto the right path. I hope you bite the bullet and do it right. Life is too short to guess about good color.
