Special color and transparency

Just recently I encounter one problem in Illustrator. Text in special pantone color applied on the background and used drop shadow. After I converted to PDF using print ps and distilled. But in the PDF, i saw some white parts came out on the text instead of pantone. So I tried another method using export PDF. The result looked fine but it came out again after went trough the RIP. (We used Fuji celebral workflow).
Anybody can help?

Sounds like a transparency issue. Here is an InDesign tip that also applies to Illustrator:

You could also set the shadow to multiply.

Spot Colors and Transparency

In posters, brochures etc. designed with gradients,(AI10) when saving, I always get the "when spot colors are used w/transparency, changing them to process colors outside of illustrator can generate unexpected results."
My printer wants spot colors and that's what he gets. I use grays a lot 'cause client can't afford colors. He prepares the plates with the required dot intensities which go to another printer who prints all. So far, things have worked out OK. However, I worry when clients want photos included, and I'm not sure what I'm doing is just luck, or the way to go.
I open a .jpg in PS7,duplicate it as grayscale .psd,adjust and drag it on to a 150 or 300 ppi transparent background and save it. It's then "placed" in AI where it's needed and finished there.
With only 1 previous experience working in this manner, the brochure worked fine. So, just what exactly is that darn warning above telling me?
Do I continue to ignore it as I did the first time? Any suggestions for working with photos? I'd like to be more than just "lucky" and not have a failed work as a final product....thanks much...........m

It's telling you that if you are printing full process CMYK, then the spot colors will be converted to CMYK and it's not guaranteed that the spot color will look the same. There is always a shift in color gamut when converting to CMYK. As you are only printing to spot colors or grey, the warning doesn't apply.

Indexed color and transparency in PNGs

I'm working with a software developer who is revising his subtitle rendering application to meet my company's specifications. The renderer produces an image sequence, and we agreed on using PNGs with a transparent background as the format for the image sequence. The renderer is producing PNGs in Indexed Color mode, so Photoshop and Windows Photo Viewer recognize the transparent background, but Premiere Pro CS5.5 and CS6 don't. I can re-save one of the PNGs after switching it to RGB mode in Photoshop, and then Premiere Pro recognizes the transparency. I'm not surprised by any of that. What I am surprised by is that the software developer says he can import the same PNGs, without switching to RGB mode, into his copy of Premiere Pro CS3, and Premiere recognizes the transparency.
Is there anything I can do besides batch processing in Photoshop to get Premiere Pro CS5.5 or 6 to recognize the transparency in an Indexed Color PNG? Has something changed since CS3? I did look under Modify>Interpret Footage to make sure that my Ignore Alpha Channel box is unchecked for the PNGs, but I can't find another relevant setting to check, and I can't figure out why CS3 would be able to recognize an Indexed Color PNG.

PNG's need to be RGB.
CS3 was a long time ago..
You can however import gif in indexed color with transparancy.

Spot colors and Transparency causing Overprint knock-out

Whenever I create a PDF from InDesign (CS3) I get missing artefacts/items on print production.
It is caused by a transparent PSD file being laid over a spot color.
I print a /ps file and then Distill to Press Quality.
Overprint preview in ACrobat Pro shows what I need by overprint off I lose info - this causes immense problems at all the pre-pre studios I use.
Any pointers to a cure/reason?
(more info if needed upon request)

For one, please do not go through PostScript , rather export to PDF directly. When doing so, you may want to do the transparency flattening either during PDF export (i.e. in Indesign) or later on in Adobe Acrobat Pro.
Going through PostScript/distilling adds extra potential for issues.
Next, any print service provider who is not in a position to deal reliably with overprints, does not deserve a contract from a high profile client. Rather, find print service providers who are up to the task. A decent print service provider should produce a result that is visually very very close to what you see in Adobe Acrobat Pro having turned on Overprint Simulation and Output Preview. If the output from a print service provider suffers from missing portions or other artifacts (as those that can be seen when Overprint simulation and Overprint Preview are turned off in Acrobat Pro) then that print service provider is simply failing.
Finally - as pointed out by Jon, the best approach is to keep the transparency in your PDFs alive and find print service providers that can deal with it (because for example they have a workflow based on the Adobe PDF Print Engine).

Is it possible to add and adjust css3 box-shadow and its effects... color and transparency with mucow?

Does this make sense on how to apply it?
#{param_itemUID} .rect{
background-color:{param_backgroundColor};
width:{param_width}px;
height:{param_height}px;
-pie-box-shadow:{param_xshadow}px; {param_yshadow}px; {param_shadowblur}px; {param_ShadowColor};
box-shadow:{param_xshadow}px;{param_yshadow}px;{param_shadowblur}px;rgba({param_ShadowCol or},{param_opacity});
Thanks!

You should be able to do those things with a mucow.
If it's not working, could you share more of your mucow - maybe just send me the whole thing so I can take a look (lbushore (at) adobe.com)

Pantone spot colour and transparency don't work together

Using indesign CS5, I make a pantone solid spot colour background.
I import two of the same photos: one a greyscale circular pshop file with transparency surrounding the circle ( the file is not flattened).
The other is the same photo, but I make a clipping path around the circle and then flatten the file and save as a jpg.
Both photos are put on top of the pantone solid color background in Indesign.
I export the indesign file as pdfx 1a using pdf-presets under the file menu.
If I open the pdf in Acrobat and open the "output preview" panel and turn off the "simulate overprinting" box, the pshop photo disappears, but the jpg with the clipping path is fine. They print as they appear: one disappears (Pshop file) and one is OK: the jpg.
If you import the pdfx 1a pdf back into Indesign, you will see that the pshop image has disappeared.
I understand this happens to others not just me. is there a fix?
Does it work with all a spot colours and transparency?
If I save as a higher version of acrobat (say 7). The pdf looks fine and imports back into indesign fine.
And if I send to the RIP the RIP seems to handle it fine. But if I take that Acrobat 7 file and put on a page and export as pdx-1a, I get the same problem

Spot colors and Transparency do not play well together, but can be used together if you follow some rules.
jpg does not support transparency. If you're working within InDesign, you can, and should save as and use psd or tiff. Tiff supports transparency if toggled during the Save As dialog.
x1/a pdf does not support transparency, hence it was lost. In my environment, Press Quality PDF has never failed me, but High Quality and x4 have added benefits of Color Management.

Watermark, color space, and transparency problem

I'm having a problem with inserting a watermark image into my pdfs.
I created the watermark image in Photoshop. It is 8-bit gray with a transparent background. I saved it as a pdf (pdf 1.4 to allow transparency).
The main pdfs (to be watermarked) are created through a seperate process (they are scans of old book pages). The pdfs are produced from 8-bit gray tiff images, but I cannot determine what color space the these pdfs are.
To the problem: in Acrobat 9, when I insert the watermark above, all of the blacks on the page shift to grey, as if the opacity was shifted lower. The opacity is set to 100%, so this should not be a problem! The watermark does have a transparent background, though.
Since this seems to be a color space conflict, if I save the watermark PDF in CYMK or RGB, it does not cause the tonal shift (blacks remain true), but the watermark now has an opaque background. I need it to be transparent, as the background of the files to be watermarked are not tonally consistent (old discolored paper).
I guess these are my questions:
(1) Is there any way to determine the color space of a PDF? File->Properties does not list color space.
(2) Why does the watermark PDF, saved in CYMK or RGB, not allow a transparent background? Is this an Acrobat issue or color space?
(3) Does anyone have an idea on how to solve this? :)
Thanks a bunch.

First, I have 2 questions: 1) How do the color and watermark background look when you have Advanced > Print Production > Output Preview open? 2) What version of Acrobat are you working in?
The most common reason that people see an almost "washed out" appearance (or looking as though additional opacity is applied) is due to a bug in Acrobat 8. This was fixed in the 8.1 dot release. One way to determine if this is what you are running into is to view the file with the Output Preview dialog open. If it views correctly then, make sure you have the update installed.
I don't work with watermarks, but understanding the general concept of watermarks it seems like a reasonable guess that they would use overprinting. I'm wonder if this is what is affecting the display of them (non-transparent background) since Acrobat needs Overprint Preview ON to accurately display objects with overprint flags . As with above, turning on Output Preview will help you deduce if that's what is happening since Output Preview automatically enables Overprint Preview (which is off by default).
BTW, Preflight will let you know what color spaces are in PDF file. Run any Profile. In the results panel, drop down the "Overview" section. There you will find a color spaces section listing the color spaces of the document.

Why can't I change the transparent color and font color in IOS 7?

Who thought all this WHITE AND TRANSPARENT color looks appealing?
Why can't I change the color of the folders and text?
I already tried inverting the colors and then it washes out the photos I use as my wallpaper.
I love everything, so far, except this transparent issue.

That's very sad those colors can't be changed. They really look ugly.
Thanks for responding.

Export Flash image to Illustrator : bad colors and no transparency

I've tried to export my vector work from Flash to
Illustrator.
The result is bad : colors have faded and transparent colors
became opaque.
It is a shame that Flash doesn't provide a correct export
function to
Illustrator now that Flash and Illustrator are both Adobe's
softwares.
Does somebody know a better way or software to export
Flash/SWF vector
images to Illustrator or PDF?
Thanks.

Photoshop Color correction and Special color Effects

Can anybody pls tell me , how they create color corrections in movies like Harry Potter, Lord of the Rings. and all the other special color themes they create different images...
I use photoshop a lot but m a amateur to color correction thing .

There are many applications, that can do CC (Color Correction, often referred to as Color Grading, or sometimes just Grading). Premiere Pro has many CC Effects, and these should be done on calibrated NTSC, or PAL, monitors, and not on the computer's monitors. One reason for this is that Premiere is not a Color Managed environment.
Adobe After Effects also has many (actually quite a few more) CC Effects, and is often used for this purpose, even if one is not using it for its normal operation - compositing.
Along with those, there are many 3rd party CC plug-ins, like Red Giant's Colorista.
Once one gets past indie films, Hollywood would use workstations designed specifically for CC, with software not commonly available to the vast majority of the public. Again, the work will be done on constantly calibrated monitors, and by skilled technicians, who do nothing else, all day long. A good starting point would be the Black Magic Da Vinci system, but this really only gets one's foot in the door.
To get a handle on CC for Video, I recommend The Arit and Technique of Digital Color Correction, Hullfish.
Color Correction in Video is a subject, where popluar books will fill a large library.
Good luck,

FEATURE REQUESTS: Border Panel and Transparency slider for bg color

Some points:
1) "Color" by itself is a dubious panel name. Color of what? Please use the existing CSS property names wherever possible, and separate out background color and border color.
2) Transparency sliders need to be enabled for all color pickers everywhere in the UI. RGBA everywhere, always. No hex colors, ever, please. There's just no reason anymore.
2) Border sides need to be separately tweenable in the UI. I've posted about this before. Here's a bit more detail: Use a 1-to-4 toggle button at the top of the Borders Panel to go back and forth between a simplified and a four-separate-borders interface. Something similar to what you've done in the Corners Panel. I've mocked up the panel UI below.
4) Hire me as junior interface designer on this program.

@Sarah:
You're right about selecting opacity in the color picker. That's probably cleaner. But it doesn't bother me in the slightest that a border with an alpha is rendered over the background-color. That's CSS. (Just use a bg color of "none" if that's what you need.)
In response:
1) Please don't use CSS "outline" for any heavy lifting in Edge. The interoperability problems are currently massive. For one thing, Firefox draws outlines outside of any box-shadow, contrary to the spec. This bug has festered for three years now, and shows no sign of ever being fixed:
https://bugzilla.mozilla.org/show_bug.cgi?id=480888
The other big limitation is that outline edges are always square, and can't be rounded. To create what you're calling an "external" border just use a box shadow with no blur. This is a standard practice, and renders well. Whatever you do, please don't make a panel called "borders" that actually creates box-shadows. The answer is education and evangelism, not mislabelling things.
2) Borders don't change the external dimensions of an element if you use border-box globally. Positioning doesn't get the least bit "out of whack." There shouldn't be any trepidation there. This is probably how Edge should work across the board, for all elements, especially if the math of box-sizing is getting you and your engineering team down For folks who aren't hip to this yet, see this fiddle:
http://jsfiddle.net/tUVM7/
and this explanation of the property:
http://paulirish.com/2012/box-sizing-border-box-ftw/
Borders and Box-shadow panels need to be in the "frontlog", not the backlog.

The following line tells me that this is not a template file, but a document created from a template called index.dwt
<html xmlns="http://www.w3.org/1999/xhtml">
This means that you saved a child document as a template file at some stage.
If you go to Modify->Templates->Detach from Template, you can remove the template structure from your document. All you then need to do is to re-save the document as a template.

I have Dragon Dictate but did not notice until now that the earphone jack is only for listening so I cannot dictate using headphones and the mic on the computer is not good enough for that. A friend gave me a USB card that says 3D Sound on top; it is a plastic case, charcoal gray in color and side jacks to connect headphone and mic. Connected to computer but it does not do a thing. Any ideas on how to make it work?

You are not supposed to connect a pair of speakers(as in left and right in a stereo pair)to two separate out jacks on the sound card.the place on the card where headphones/speakers with the mini jack goes is the right place.

How to get the color interpretation ( transparency/opacity)

Hi all,
I am trying to translate colors that may be affected by opacity & transparency into a strong color.
Input colors may be RGB, CMYK and LAB.
Right now, I am :
1) duplicating source color (because Paper/Black can't be tweaked, I need to work on a copy)
2) Setting duplicated color space to CMYK
3) creating a dummy color in CMYK
4) affect CMYK values of the duplicated color by transparency and opacity
ie : source color is Black [0,0,0,100] at 50% opacity and 50% transparent ( frame effects) => [ 0*0.5*0.5 , 0*0.5*0.5 , 0*0.5*0.5 , 100*0.5*0.5 ] = > [0 , 0, 0, 25 ];
5) setting dummy color space to source color space
6) Do my computations based on dummyColor
6) remove duplicated color
7) remove dummy color
The process is working but deltas on teh colors are a serious issue. Not big deltas but enough to corrupt the trust on the color interpretation.
SO question is : Is there any way to get a correct interpretation of a color affected by opacity/transparency settings ?
Do you have any link towars an understandable paper about how lab/rgb and CMYK colors are affected by opacity/transparency ?
Thanks in advance,
best,
Loic

@Loic – nothing much to offer here from my side. Just a source by Adobe which is very likely outdated, but you can look for hints doing research on the theme:

SVG to PDF/AI gradient and transparency issues

This is probably quite off topic for these forums, so apologies for that up front, but I can't seem to get answers in more appropriate places.
I am trying to use inkscape or rsvg-convert, which both use cairo, to convert SVG to PDF.
Firstly, when I open the SVG in Illustrator directly, everything works as expected, but the cairo converted PDF has a couple of problems.
Typically I get "An unknown shading type was encountered" and the offending shapes are un-editable "images" with a clipping mask over them.
There are two circumstances that result in problems for me.
1) A gradient with only 2 stops.
In the following example I have duplicated the offset="0" stop which fixes things and means that the resulting shape that is filled with this gradient works fine. Without the duplicate declaration, the gradient is converted to an un-editable image with a clipping mask when the PDF is viewed in Illustrator.
   <linearGradient id="ian_symbols_b8a58aafc1f12e74492e9e865b7f569b" gradientUnits="userSpaceOnUse" x1="113.7275" y1="136.9414" x2="197.0259" y2="136.9414">
    <stop offset="0" style="stop-color:#927A62" id="stop1472" />
    <stop offset="0" style="stop-color:#927A62" id="stop1472_dup" />
    <stop offset="1" style="stop-color:#93866F" id="stop1474" />
   </linearGradient>
2) A shape that has an opacity that is less than "1". I don't know how to fix this one and still maintain the look of the original. I understand that there are some issues with transparency and the PDF format, but obviously the full AI version of the PDF format these days supports transparency.
Does anyone have any experience doing server-side conversions of SVG to PDF and have managed to create a PDF which contains gradients and transparency that are actually editable once opened in Illustrator?
Or does anyone know if there is something more I can do with the original SVG code to make the opacity work ok in the final PDF?
Thanks

Works fine for me as .ai with pdf comptible turned on. You may have input transparency in the wrong location in Illustrator. Change opacity in the gradient palette, and not tint in the color palette.
Opacity is 0 here, anything less tha 100% will create tranaprency. To proof in Illustratopr do a Shift Command D to change your background to a checkerboard pattern.
