View 2 RepliesMy company is switching from ctb files to stb files. With the ctb file, we make concrete hatch with two layers. A top layer with the concrete hatch pattern and a background layer with a solid hatch patern. The ctb file concrete plots the concete hatch black and the solid background hatch light gray. I am using civil 3d 2013 and the hatch allows a seperate background color mask. I am trying to make all my concrete layers (Top of Curb, Curb Flowline, etc.) a certain color scheme, i.e. shades of green. I would like my on screen concrete hatch patern to be a green color with a gray background, but plot the concrete hatch black with a gray background. I can not figure out how to do this without making two layers. Is there a way to use one layer and utilize the background color mask to show on screen green and gray, but plot black and gray?

View 9 Replies View RelatedGroup, I just got CS4 and I am working in RGB and when I hit D to set default colors the black is not black... It is a dark grey. Basically the same if you take something that is black in a CMYK document and paste it into an RGB document. The black becomes gray. Can't figure out what color setting to change to set blacks as "Rich Black." Under Edit - Preferences - Appearance of black, it is set to Rich Black.
View 8 Replies View Relatedwhat would be the CMYK value for "70% Gray of 100% Registration Black." A teacher from school has asked me to print the type for a poster in that color, expressing it that way, and I'm not sure what he means. From my understanding, 100% Registration Black is C: 100, M: 100, Y: 100, K: 100. So how would the 70% change that?
In case you need some frame of reference, I'm working on a poster for a class that has to be printed in a particular way for a Photolithography class. I'll be making two files, each of which will have the info for one of the two colors in the poster. Those files will then be made into films which will be printed.
Art brushes are showing a grey version of what should be a Rich Black RGB 0, 0, 0,. Furthermore, expanding the art brush stroke and sampling the color shows the strokes "Black" is actually: 32,32,32, pre-expansion the RGB sample shows the stroke is 0,0,0.
Color Mode=RGB
Print Proof=NO
Document =RGB
Display all Blacks, print all Blacks=Rich Black
Options for Art Brush show art brush swatch is Rich Black but using eyedropper (within brush options window) and sampling preview stroke CHANGES swatch preview from Rich Black to Grey.
I am a Paramedic Instructor and want to clean up some heart rhythms to make them more neat and presentable for use during class. Below is the sort of image I would be working with.
What I would like to do is remove only the black and gray lines (when they print out of the EKG machine some lines have some gray in them) and place them on a neater cleaner background as below
(The image above I found on a website where the creator has 100's of EKGs that this has been done with, but have been unable to get him to tell me how it was done)
Also let me know if another Adobe product would be more useful in this situation. I have CS6 Master Collection so you know what programs I have available to use.
Gray / black halo around feathered transparency objects. The halo occurs where the solid area of pic feathers to the transparent.
NOTE: Image looks fine in Photoshop(CS6) but when placed in Indesign (CS5) a black halo appears on page
This only happens when image is an RGB Tiff and layer mask is used to create transparency. If image is saved as .psd then it is fine. Also when RGB tiff is converted to CMYK then this is also ok.
Ideally I could just start using psd format, but I have to handle a lot of images that are already in RGB tiff and it is time consuming to have to open and re-save all of these.
Photoshop CS5 RGB tiffs are still working fine.
I have a TIFF file of a scanned microfilm page of a very old manuscript.
The background of the black fonts is gray, and it makes the reading of the text very hard.
My question is: is there a simple way to extract only the black fonts of the text, or otherwise to brighten up the background?
I'm trying to put some black hair brush strokes against a head and they will NOT turn black no matter what I do. I have checked the color tab to make sure it's set in RBG.

The screen portion is supposed to be white, as well as the buttons. The border of the black section is gray, as is the edge of the phone.
I have a blue shape with a feathered edge on a black background. The color transitions from blue to grey to black. I want to transition from blue to black without the soft grey line.

I recently bought a new pc and installed Corel Draw X5. When I export to eps and open the eps in Corel, the Pantone colors appear nearly black. This is also true for my clients, although I'm not sure what program they are using to open the eps.
It is worth mentioning that on my old PC I did not have this problem. EPS files I exported from Corel Draw X5 were fine. I could export eps files containing Pantone colors, and the Pantone colors would be there when I opened the eps file.
The settings I'm using under export to eps dialogue are the exact same settings I was using before:
Output colors as Native and PostScript 3.
I am running Windows 7 Home Premium SP1, and CorelDraw X5 15.2.0.695
I have Photoshop Elements 8 and just recently it changed a bit. When on the active tab (any tab) the background outside my working space is completely black instead it's usual gray. I don't know how it happened but I would like it back to normal. I've attached my screenshot below.
View 2 Replies View RelatedI have been working on a large number of sketches. At this stage I am just using the path tool to make the outlines of my cartoons.
I have got fairly confident with the path tool now, however on my first 3 pictures my paths were a mess. The first 3 pictures I stroked the path at 10 pixels, I would like to reduce this to 6 pixels. I am not able to go back to the original paths so I guess I need to select lines from the completed pictures and and convert these to paths, then restroke.
I have been trying to select by colour (it is all black) but that gives me the outline of the black, ie, a double path. I have tried selecting the back ground and expanding it by 2 pixels, this worked but not in tight corners.
Using CS5, dropdowns are black, gray text, some positions require hover to see text. How to fix?

I am attempting to plot a drawing that was created from a template into a .pdf but it is plotting colored lines instead of black lines.
Here is some background info. My template is set up as a .dwt which I will save as a .dwg when I begin to make my drawings. Plot style table is “monochrome.stb” and I have selected Adobe .pdf as my plotter configuration. I then select the “Properties” then go to “Custom Properties”, “Paper/Quality” tab and then select “Black & White” as my color.
When I go to plot the drawing as a pdf and do a preview of what I am about to plot, I see that the lines that make up the drawing are a shade of gray in color. All my lineweights in the layers property manager are set to default. I have attached a blank drawing that is based off of my template.
Basically if I select a color and apply it to the image it turns gray. [URL]

View 2 Replies View RelatedI have another question about GREY images.
Example: CTRL+click on grey channel theoreticly (by my theory) make selection from white depending on its value. So cuting out must leave transparent greyscale image. But it don't (okey, it do, but changes black value):
The same selection inverted and filled with 100%K gives correct result: Is my "theory" about CTRL+click selection wrong? Becouse for my point of view, both ways should give same result.
Total buffoon when it comes to getting GIMP to do what I want to do. I'm just practicing with making maps, black lines on a white background, and I've run into some issues I'm wondering if I can get rectified.
1) For whatever reason, the line weight of everything has shifted throughout the file, ending with some lines lighter and grayer than others. Is there a way I can get GIMP to trace all the lines in a uniform black, with uniform thickness?
2) I have tried locking the white background, but often when I select and move my black lines, if I don't click in just the right spot it moves the white background instead, which is really, reeeaaaly aggravating. How Do I get that background to be completely untouchable?
3) In trying to colour the image, I've run into problems with their being a white outline between the colour and the black lines. I think I need to sharpen the image or somesuch? How can one correct this issue?
4) Is there anyway to convert the black dotted lines of the paths tools into straight black lines, in regards to an older file? If not, is there an easy way to trace them?
5) I find the scale too tends to make my image too jagged. I want to take a section of my map, move it too another file and enlarge it to do detail work - what's the best way to do this in order to have a clear image?
6) Any way to translate an image from a MErcator Projection ot a Winkell-Trippel projection, one that works on a Mac?
Why does a black through white gradient created in an RGB document have a B channel that differs from the R and G channels?
In 8-bit mode, only some of the "grays" have a mismatching B value and there seems to be more of them when the gradient is created by Gradient Tool than when it is a Gradient Fill layer. The difference seems to be 1 in the cases that I've seen.
In 16-bit mode, I see the B differ from R and G by 7 at black, gradually reducing to 0 at white.
Before someone says, "Why make a fuss about small discrepancies?", I'm asking why there is any difference at all.
Im trying to get rid of the black and white lines in this picture .
View 2 Replies View Relatedmaking a alpha channel transparency; Funny thing is. I made it work once a few days ago. I went to bed and forgot to write down how i did it (Tried everything, almost)
In the link right here [URL] n i have 4 files; Q3a_arrow_gimp_ver4.tga (TGA that works as i want it, you'll notice ALL the alpha channels have a black layer channel in the channels tab, how do i recreate that?) Q3a_arrow_methodtry.tga (tried to recreate with THIS tutorial [URL] with no success P.S. i tried loooads of tutorials but this recreation seems rather close to the working .TGA i need) Q3a_arrow.ai (sourcematerial all vector from Adobe Illustrator) Q3a_arrow.png (picture with transparency intact if needed for comparison)
So; Now... What i did to make the working picture was making a .PNG - drag it into gimp.. I recall doing some Alpha and or masking or selection thing with it, then rendered it for .TGA since Illustrator does not support the kind of .TGA i needed. Worked flawlessly in the engine where i use a function called alphafunc GE128 (blend with black as invisible layer and white as solid)
