I am a screen printer and I print my separations from Photoshop. I routinely work with multi channel files or RGB files with additional spot color channels. I have created actions to place my registration marks, re-size images, etc to get ready to print but I manually have to create the text labels for each screen if they are missing from the original artwork.
The files I work with have channels named as "Base White, Red, Green, 284 Blue" etc indicating the ink color. What i would like to be able to do is click an action that would copy the text from the channel name and insert it into a separate or each/all channels near the top of the file so that when I print each positive it has a corresponding label for ink color.
I am not sure if this is even possible, and I am limited on my knowledge when it comes to actions and have pretty much got lucky in the past getting them to do what I want without unnecessary steps.
On my registration target action it creates a new channel with each individual reg mark then combines them into one separate channel in which I just copy the contents and select all the ink channels and fill with black to make them appear, i'm happy with the steps it takes as it isn't too much trouble and if this could do the same with labels I would be happy with that.
Just made sure updates for the video card and all the hardware were current and still getting this problem where when I go to adjust a channel of video a random frame from the below channel will insert itself into the clip that I just moved as if it was married into the source footage.

How can I get the channel subassembly to attach to the assembly insertion point at the channel flowline marker? Â I need the flowline to follow my profile elevations.

I would like to manipulate a channel from Calculations with

What is the more usual image mode? I think my files have been 8 bits per channel for many years. I was having a lot of trouble with Photoshop slowing down dramatically on several large files I created, and I noticed I had made them in 16 bit mode. Would this require more RAM?

I've another damaged picture and looked at the channel saw the red is better so clicked all from selection and copied it and scrolled down and pasted into in the green channel. Is it correct?
I have just installed.
Photoshop CS4 Extended as part of the master suite.
I have also CS3 on the same PC.
Now the channel mixer doesn't show the sliders for tint (hue and saturation); the same happens on the B & W adjustment window.
I try to run CS3 (shortcuts or the program itself), CS4 comes up instead.
What's alpha channel & how to use it?

View 1 Replies View RelatedI've been colouring an image which was black and white, consiting mainly of black lines. I've made a special channel for the lines and coloured it all in the RGBs chanel, and now when I want to save this as an jpg or at all, the lines vanish. The chanel and the original pic is still there but the lines just won't apply to the rest of the art so they coul be seen, only when I click on the visible or not button at the channel. I've tried to merge it but it still only gives me the colours of the pic without the lines..
View 3 Replies View RelatedI have created two masks with channels to use on an image. Now I want to combine the two channel masks into one to use. I made a new layer in channels of the composite masks which gave me an Alpha channel. The Alpha channels show the solid black paint lines where I filled in the selection voids. These solid lines affected the adjustment layers so I ended up doing some erasing at 50%. Not the shortest workflow direction. How can I combine two channel masks (selections) into a common selection and save as a new Channel?
View 7 Replies View RelatedI created an alpha channel with marquee tool on a colored backgound, by using "select > save selection", the alpha channel appeared at the bottom of the channel palette. I know the white part should represents transparency and the black part is opaque. But when I import this into the Adobe premiere6.5, the thing is reversed, I have to use "alpha channel" plus "reverse" option to get what I want - see through the "white" part. I heard there is an option in the photoshop with which you can define whether you want "white" is transparent,black is opaque or vice versa,
View 8 Replies View RelatedI apparently changed something in CS3.
I frequently change the mode of my images from RGB to LaB to do various tasks. Now when
I convert from RGB to LaB the LaB channel is black instead of displaying the image in LaB color. For the life of me I can't see what I changed.
I have an image that I want to have an alpha channel even though it isn't used at all. Even if I save the image with transparency flag in "Save for web" (as PNG), Photoshop doesn't include the alpha channel with image because it's not been used. Is there a way I can overcome this (other than adding a single transparent pixel to image or using another program)?

I having a problem with creating a new channel in that when it is created the image becomes white instead of black. I need it to be black to create the red selection, when I click the RGB channel visablitiy " eye".
I have tried changing the colour in the new channel dialog box and it doesnt make any difference. Still get white. Also have tried changing the white to black by pressing control backspace to fill with black but then I still cannot get the red selection . I Would really apprieate some help with this. I am doing this tutorial and I am stuck at the moment.
When I try to save a selection to other than a New channel, the Save Selection box only allows saving to a New channel and grays out the other options. How do you save a selection to another channel and/or activate the other options?Â

View 2 Replies View RelatedOnce I create an alpha channel, how do I edit it? I have tried selecting and clicking the alpha channel, and then using the paintbrush tool. I understand that if I have a white foreground, painting should remove some of the mask, while a black background should result in the painting adding to the mask. But often nothing seems to happen when I paint. Or, at other times, the painting results in paint marks on my image but doesn't affect the "marching ants" and therefore doesn't affect the mask. I have already checked that my K setting in Color is at 0 for white and 100 for black. Using CS5 version 13.0 x64 with Windows 7.Â

Color is correct in all other programs and my monitor is correctly calibrated using Huey Pro. Attached is a screen shot of a side by side of the same image displayed in IrfanView and in Photoshop.
Does the 32 bit per channel retain the sign if negative through processing, saving and then reading? It is advertized as floating point.Â
View 4 Replies View RelatedFirstly, what does a person do when they need 57 channels (56 being the top limit)? I am sure that large projects go OVER 56 channels. I can't be the first person to ask about this issue, yet I can find nothing on "the 57th channel."

Secondly, why is there (what seems to be) an arbitrary limit of only 56 channels?

No place can I find details about the 56 channels, and how to deal with when you need more channels.
How do you create a perfect alpha from this image, channels don't work, selections don't work either very well. I haven't done something like this for a while, so maybe it's a brain fart, who knows

Take a gradient, from Red 100% Opacity to Blue 0% Opacity. After I saved the gradient as a PNG, how can I for example use the levels adjustment on the PNG's alpha channel?
If I open the image in After Effects there is an option to control the alpha channel. That's quite embarrassing if a video software can edit the alpha channel and an image software can't...
I've attached screenshots to demonstrate what I mean.
I am trying to select the aplha channel (and make it a selcetion ) by using the command +mouse click but I only get the black selected not the white. So i have to invert selection, which is annoying. Am i missing something? this worked 2 weeks ago and now it has changed.Â
View 3 Replies View RelatedI've got an RGB image, but each pixel actually has identical R, G, and B values-- the image is just varying degrees of grey. (It's not actually a greyscale image, long story. :P)
If I click on the single channel view, it's much brighter than the RGB combined view. Each channel appears identical to each other channel, but they're all considerably brigher than the combined RGB image.
Do you know what adjustment is being performed?
(That's the short question; elaboration follows.)
Photoshop is aware of this adjustment, and will replicate it if you copy the RGB image and paste it into a single channel of a new image. For example, I can copy the entire image, create a new image, and then paste into just the red channel of the image. Visually, the combined RGB view of the source image and the single channel view of the dest image will look identical.
How was this achieved? Photoshop darkened all of the values: a pixel that was 24, 24, 24 in the source image is now 7 in the new red channel.
I haven't been able to replicate the conversion. Visually, it looks a lot like a gamma adjustment, and values in the middle range roughly approximate an adjustment using a gamma of 1.266 (which seems odd, so is likely not what's occurring). Values in the lower range, however, are darkened further-- a gamma adjustment of 1.266 will leave them too bright.
I'm developing a tile based game, I have basic ground tiles, and above these tiles can be objects. My game engine supports objects with an alpha channel, where the alpha channel is used for transparency:
alphachannel 0 = completely invisible pixel
alphachannel 255 = opaque pixel
alphachannel between 0 and 255 means the object and the background tile below that are blended, like semi-transparency.
This is useful to give the objects soft edges, and for semi-transparant fire, ghosts, and other nice looking effects. Code:
