DCS Tranparency Ai10

Linked Artwork that interacts with transparency cannot be flattened. Embed the artwork( using the links palette) before flattening

We are placing FPO’s off our server.....What is this message trying to tell us?

[Mordy_Golding@adobeforums.com]

DCS workflows are not supported in Illustrator 9, 10, or CS.

In other words, you can't place low resolution graphics in to Illustrator and have them print correctly. There are times when Illustrator needs to "flatten" files (not the flattening that happens when you collapse layers in Photoshop) and to do so, Illustrator needs the hi-resoution version of the image inside Illustrator.

Mordy,
And Adobe wants us in newer Ai versions because..........?

They have added a lots of support in Indesign CS for DCS1, 2.0 and
transparency. We hope this can be also included in the next release of
AI.

LowRes and/or FPO is not and will never be supported (at least not soon)
in transparent documents.

I think that Adobe looks at DCS as being a workflow that is old and has shortcomings. One of the interesting features that you can find in InDesign CS is support for Photoshop Spot color channels in a PSD file. I'd think that Adobe would sooner support that in future versions of Illustrator rather than support DCS.

It's been many years since I've used a DCS file.

If so, why does the Indesign teams Support DCS1, 2.0. They spend times
and money making it works in IDCS. So, it is probably the illustrator
team that find it useless and old...

Sure, if the next AI support full .PSD with spot that would be good. And
why not PS PDF also.

AI CS already offers way more support for spot raster data regarding .psd and Photoshop pdf files than dcs images can offer.

See this thread. <http://www.adobeforums.com/cgi-bin/webx?128@@.2ccf18e7>

[Jean-Claude_Tremblay@adobeforums.com]

Yes, AICS have made some enhancements in that regards, and it¹s possible
to use .PSD with spot color and even with PDF, You need to turn on
Overprint preview to see the spot color (in PDF) and create a spot
swatch before importing .psd to see it in color on screen.

DCS was widely use and still for people doing packaging... Their is
still a need to offer support for it in my opinion.

I hope you also know that you do not need to add a spot swatch if it is a psd CS file.

DCS (IMO) was a workaround and should have been killed off long ago. Regardless if DCS is still used, the format has serious limitations.

Yes, I put blame squarely on the Photoshop team for not making the photoshop eps format retain spot color. (I also understand why they did not and focused their energies to other areas, but still I will whine and complain to get my way. ;))

Please, give me an example of how you would use a DCS image in Illustrator that a PSD or Photoshop PDF cannot accomplish?

No i was not aware of that... My test a few months was with PS7 and AICS.

I agree, but some peoples have may legacies DCS file use in AI. Forcing
them to resave it as .psd is not a solution.

I don¹t have any example, and this was not my point anyways. By the way,
i have stop using DCS a long time ago also... But some of our client
don¹t.

You hurt me. You did not read that main post in the link I referenced that pointed that out :( (I posted that topic)

The reason I questioned was not to be combatant. It was to gain new insight that I was unaware of. Even though I will always claim I know everything, I really do not.

John, sorry i did not went to you link, i¹m reading the User To user
forum with a news readers, so i need to go back and read it with
Explorer. I will..

One, think i have found and i would you to test also to get sure it is a
reproducable bug.

Here is the bug i have found with placed .psd with spot color.

When placing a .psd (linked) with spot color channel in AICS and later
manually embed it with the link palette.. The Spot channel are not
embeded with the same coordinate as the main CMYK channel. This is also
treu with grayscale and spot color .psd.

In fact, two thing can happens...

A) If you have not resize the .psd, the channel are not place with the
correct x, y, coordinate.

B) if you have scale the .psd, the main CMYK % will be retain when
embeded, but the channel color are not. In fact, AICS does not retrain
any transformation done on the .psd before embeding. (EX: If i scale
down the .psd at 25% and rotate 15?, then embed it only the main CMYK
image keep the transformation, the color channel don¹t)

Ok, now i will go and read your link.. on the web.

[Jean-Claude_Tremblay@adobeforums.com]

Ok, i went to the web, and i remember seeing and reading soem parts of
that thread you are talking about.

I will reread it completely... and maybe add my comment if needed.

Regarding the misplacement of spot channel when embeded. You workaround
to convert to Object layer is not good when you have a single layer
flatten .psd. Their is no such opetion with that kind of files.

JC

[John_Kallios@adobeforums.com]

Yes, you have to go back into the Photoshop file and convert the background to layer.

[Jean-Claude_Tremblay@adobeforums.com]

An xtra step not needed...

I know, hopefully the bug will be fixed in the next dot update. It IS a bug that needs to be fixed.

[Jean-Claude_Tremblay@adobeforums.com]

John,

take a look at this gif...

[url]http://www.quadriscan.com/files/spotcolor.gif[/url]

it¹s a attempt to get a clear understanding of what is and is not
supported with spot color and Indesign/illustrator transparency.

This is something i have written a few months ago (january). Tell me if
their is anything that is not correct.

PS: This is for image with spot color that interact with transparency
inside ID or AI.

JC

[John_Kallios@adobeforums.com]

Everything looks pretty good in the gif image.

Small correction for the Tif format.

InDesign CS does support the tif format with spot color and transparency whether the transparency is within the file or applied to the file.

My assumption to the table in regards to transparency is that it referrs to transparency applied AFTER it is placed in the application. (Not saved in the file)

[Jean-Claude_Tremblay@adobeforums.com]

Thanks for the corrections on tif support with IDCS...

I have reread all of the others thread you have started, and i must said
i agree that we need better spot support in AI for next round of
release. In fact, we need a full support of it in all adobe apps. And we
need that all file format be supported independantly from his content
(process, spot, rgb) along with transparency. If we can create it in PS,
we must be able to integrate them in others adobe apps along with
transparency. I know it¹s a bit utopic that we gonna have it, but at
least we need one file format that will support all of that so we can
stick with that format, either .psd, .tif or PDF. My choice will be PDF,
the PS teams need to allow transparency to be saved and preserve in PDF.
