Hello, friends, recently we have a Service Pack that has solved many problems of the original version, but surely there are more things to solve. I want to open a list of ideas and suggestions, so as to correct errors for a second package. If someone wants to say something to the Corel team, this is the right place, for sure they will read this post.
Enjoy CorelDRAW!
Ariel:
Thanks for creating this thread!
!!!!AN IMPORTANT THING!!!! Keep this thread as direct and clean as possible so won't miss issues that people are running into. If there is a previous problem that you posted on, that wasn't fixed in SP1, please provide the link to the original thread. If there is a tangent to an issue you would like to discuss, please have a pm or start a new thread.
Thanks all!

Color Management.
While X5 offers much more indepth setting, it has also introduced a layer of complexity.
In X4 I just selected Color Management and then hit CMYK or RGB, and the color representation changed on screen accordingly. Now there are many ISO standards listed and I cannot figure it out.
I have many CMYK graphics I have sent to professional printers that now look different in X5, with my CMYK bitmaps looking washed out.
If I open that very same graphic in X4, select CMYK it looks different.
Is there anyway you guys could add the option in the Tools menu to select RGB or CYMK so non print professionals (who do a lot of print work) know where we stand.
Tools > Color Management > CMYK
or
Tools > Color Management > RGB
Opening the current Document Settings just looks confusing to me. Is anyone else in the same boat here?

This is one of the best ADVANTADGES of X5. With X4 most people just select "CMYK" or "RGB", or "Optimized for professional output", but.... if somebody ask what is your color profile, they don't know the answer. "Color Profile? I use CMYK" But colo management is not so simple (unortunately). When you receive images such as photos downloaded from intenet, other photos from a high resolution digital camera, other from scanner, and other frm unknown origin, some images with one RGB profile, other with a different profile and other whitout profile, and you must send all with the same color, you need to specify what color you want. I not the same a perceptual rendering indent than other, for example, is not the same to use coated paper than uncoated paper. Altough seems the same, the results is not the same. And you ust to adjust your color for a good result. The only way is to use a color profile, but you must know what color profile you're using, not a generic RGB and generic CMYK

... with my bit of colour theory and signal processing background, it seems like there shouldn't be anything changing in an image when you go from RGB to CMYK (or vise versa). I notice this weird phenomena in x5 too.
There is almost a 1:1 relation in the math to convert any RGB colour to any CMYK colour. Nothing should be obviously changing... especially when the percetual option is on - which I use too, but it doesn't perform as I'd expect. This goes the same for convertion to and from HSV, or whatever other colour space. There may be a tiny change due to integer round off, but it shouldn't be really noticeable (especially if the math is done with floats and the final values are rounded to the nearest integer). The lossiness is almost negligible.
Like
http://web.forret.com/tools/color.asp?C=0.000&M=1.000&Y=1.000&K=0
says, converting to CMYK is a little lossy, but RED should still look like RED in RGB, etc, etc, etc. I haven't tested their colour conversion, but the math is pretty easy.
Of course the gamuts of the output whatever need the colour representation in CMYK most likely (eg. printers), so some colours might seem to change but very slightly (and most of the change is because it's a different medium... colours on white paper instead of additive coloured rgb lights). If I simply change the colour space from RGB to CMYK, while using the SAME MONITOR (displaying RGB all the time because of the pixels), the image (and the swatches) should be exactly the same before and after. So, my wish is that the colours in the RGB swatches are the same as in CMYK swatches. This limited gamut by the output shouldn't affect my use of RGB or CMYK in the program.
However, if the settings had options for limiting or changing the colours based on my specific printer (or whatever I'm planning on outputting to) on purpose, then it would make sense that changing from RGB to "CMYK Samsung colour laser" would actually alter what I'm seeing in the working space. It seems this is maybe what they're doing, but without saying so. I'd rather be able to work in CMYK (with the benefit of changing black independently) without being sort of talked down to by having the represented colours changed to what is anticipated will be the output... unless I ask for it. However, I bet there are tons of experts/professionals who'd disagree with me on this wish.
I also have a hard time navigating the literature on the colour settings.
Not to be a nag, but it sounds like you're experiencing bugs... maybe note them in the bug thread?

... obviously you want them fixed for sp2, and hopefully corel will deal with the needs (obvious bugs in the bugs thread) first.
Speaking of wishes for sp2, I have the "Grow Mode" (for cropping bigger) icon in my menu, and it would be great if the program would remember that I want the option on (or off) when I next open PP. Also, the mouseover caption should read "toggle Grow Mode"... not "switches to the Grow Mode"
Paul McGee said:Sirry, you're way off here!!!
Let me try it again from this angle... have a look at the colour picker image below from:
http://www.webtoolkit.info/javascript-color-conversion.html
I know that the colour gamut of the printer is different... but I'm trying to say that I'd like to be able to work in cmyk without being forced into the printer's gamut and palette.
... as the colour picker in the link shows... RGB and CMYK and HSV (or HSB) and Lab can peacefully coexist without the palette necessarily changing. One can drive the other and vise versa (for ideal colours as you say).
I think my inability to understand how Corel handles "color modes" versus "models" versus "profiles" was getting me in trouble.
... another help related wish... If you go into help and search for PP's "proof colours" setting, nothing.
It's probably just me, but a bit better documentation would be very helpful. When I switch the color mode to CMYK, I was expecting to work primarily in CMYK, but still have the same (monitor output) palette, and not have any restrictions or palette changes. I didn't understand why the palette would change... I think I kinda get it now.
It seems weird though (I still don't get it)... when making a new doc in PP, set mode to CMYK, ensure the bg colour is bright white, set profile to Web Coated (which is the default)., and change the rendering intent to absolute colorimetric (or any of the others)... hit OK... then the new image background is tan colour. The implication is that white in CMYK is tan (?)... which obviously isn't right. I was reading about the rendering intents and absolute colourimetric should do a good job of preserving the colours... "If no match is found for the source colors, then the closest possible match is used"
I explicitly asked for the background to be white, but it changed to tan? Is tan somehow the closest match to white? What I'm learning is that I should be working in RGB.
I digress because I obviously have very little idea what these settings are doing.
Another wish... I'd like the colour picker to allow a few different color models for picking at a time (eg. RGB + CMYK + HSV + Hex) without having to use the colour model dropdown control. And, make it resizable, and just as functional as a docker that can be open all the time (wish is for PP and Draw).
eg. (this one's not as pretty as Maya's colour picker, but shows the ability to have various models driving the colour choice at once)
... also, see the checkbox for only allowing web colours... I was expecting something like this for print media
... that's what would optionally restrict the gamut shown on the screen to CMYK laser printer on matt paper, or CMYK laser on shiny paper, CMYK plastic banner, CMYK t-shirt or whatever the output intent is.
The trim/shape tools don't work on master layers - I just get a message saying nothing has changed. If I turn off the master property of the layer i can trim objects with no problems.
