Will the real working space stand up

Hi Everybody,

Will the real working space stand up.

All is well. Here's how to choose the "working" space in DRAW. That's the space used by the tools in DRAW or any other graphics editor. Its displayed as best as can be by the monitor using the information from a profile from DRAW to the Profile Connection Space (Lab or XYZ) to the monitors profile (plus a ton of stuff in the graphics card) to what you see on the monitor.

It's cleverly disguised under a special Corel name. I would guess that the additional two documents in different modes are obtained by using the appropriate profiles. It's beyond belief that you can "work" in three color modes at the very same time.

The primary color mode is not a working space in such that it changes your working spaces, it only controls the default palettes that CorelDRAW will display when selecting colors, it changes how the application renders transparency as well as other color oriented effects. The 3 document color spaces still tag the file contents.

The real mind binder is that CorelDRAW can actually work in 4 color spaces, RGB, Grayscale, CMYK and N (spot color) simultaneously including transparency.

And the real killer, while it works in 4 color spaces it can soft proof in a 5th color space.

Like I said CorelDRAW is a professional graphics application, it is not Illustrator or Xara.

It is the only application with a live high resolution preview in 3 color spaces.

Hi David,

Phil: "That sounds unbelievable to me. Graphic editors do arithmetic on the numbers in the document. For instance, Photopaint can have two or more layers and layer masks. Let's say the top layer is in the Multiply mode. Photopaint literally multiplies the numbers on this top layer with the corresponding numbers on the layer below.

Are you trying to tell us that DRAW repeats the arithmetic for four sets of numbers. What for? It can transform between color spaces just before SAVE.

Did you see the program code for DRAW. Did you see the system specs given to the programmers. Did you ever see any documentation to support your claim.

I find it impossible to believe you without reference to some documentation. It sounds like you just made it up.

Once again, the monitor will display color as best as it can from one color space. It's beyond belief that it is showing some strange display which includes both an image in ProPhoto and another in CMYK.

Where did you get the idea that soft proofing is done in DRAW.
Soft proofing to me means that the monitor will display how the file will look like when printed. That has nothing to do with DRAW. That's handled by the Windows Color System using the two way color profile of most printers. WCS sends the DRAW image from the Profile Connection Space (in Lab or XYZ) to the printer. The printer's profile converts the numbers in this file to printer space numbers -- as best as it can. The printer will very likely not be able to reproduce all the colors that it gets from the image. So it sends the image back to the Profile Connection Space with the colors identified as those that will print. If you ask for a soft proof or preview, the WCS will steer this image to the monitor.

You can see this a lot more clearly in a few of the diagram in Real World Color Management. Give the book a try. You might learn something.

I helped starting back 12 years ago testing to develop the color engine for X5.

I'll make you a promise, figure out the fill tool and I'll demonstrate CorelDRAW X7 working in RGB, Grayscale, ONE CMYK color space, produce spot color vectors and transparency then soft proof it all to another CMYK color space.
