HELP! Converting RGB to CMYK

Hello everyone,

I've made a recipe book on behalf of a charity and am now ready to print to get it out in time for Christmas. I've merged each layer group down so that each layer is now a whole page. However, I'm struggling to convert to CMYK in version 2.10.18. I have downloaded the ICC colour profiles from adobe. I also downloaded the gimp version from partha.com with all of the plug ins already installed. However, when I went to image> separate, there was no option to separate and I'm not sure where to get the plug in from for this version.

I am a bit of a novice so would really appreciate some help! Thanks so much in advance!

Gimp 2.10.18 ? from Partha. Is this a Windows version or Mac version? Anyway.

The plugin Separate+ has not really worked since Gimp 2.6, Barely with a few tweaks in Gimp 2.8 Definitely broken in Gimp 2.10

There is an alternative, Cyan see: https://cyan.fxarena.net/ which can be used stand-alone or with an associated Gimp plugin

There is a long thread here on installation and use. I will pop a link in towards the end but do read all of it. https://www.gimp-forum.net/Thread-CMYK-color-mode-Gimp-2-10?pid=19264#pid19264

There are other considerations. Do you intend to submit to the printer as a PDF ? Do not use use Gimp, use the free DPT program Scribus.

Just one or two pages with illustrations to convert ? Maybe do it on-line. see: https://www.rgb2cmyk.org/

HELP! Converting RGB to CMYK

Hi Rich thanks so much for your response! It's the windows version.
Okay that's good to know. I'll try that plugin thanks so much. Yes it's going to the printers as a PDF, and there are 138 pages all as layers.

Sadly I found out about Scribus too late, and I don't have time to make it all again. Do you know of a way of importing xcf file into Scribus? I've found talk of it on the internet but can't seem to put it into action.

AFAIK No real easy way to go from many layers in Gimp to many pages in Scribus. Scribus is frame based - text frames - image frames, so every page needs to be copied and pasted bit-by-bit Gimp-to-Scribus and formatted as well.

Scribus keeps text as text, embeds the text font information in the PDF and is the way to go.

The problem with Gimp PDF is that embed text part is broken. Make a PDF with Gimp and it looks great on your computer with all your installed fonts. The PDF gets to the printers, they do not have the font(s) installed. Your PDF looks terrible with default replacement fonts.

Not the way to go but you can

1. Export your document as a multipage tif file 2. Use ImageMagick www.imagemagick.org - a command line application to create the CMYK PDF.

What are the snags ? Text is no longer text, it is flattened into graphic (raster) format. Each page is a 'picture' This was the default for Gimp 2.8, nothing new.

the command is

magick -colorspace cmyk -profile .pdf

You need that .icc file so a basic generic CMYK.icc attached

..and a 4 minute example video to go with all this. https://youtu.be/35rKA8Bs71E

best of luck

HELP! Converting RGB to CMYK

Hi Rich,

Thanks so much I really can't tell you how much I appreciate your help!

I've followed all of these steps but keep getting an error message in the command promt: magick: unable to open image 'newcompressed': No such file or directory @ error/blob.c/OpenBlob/3537. magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/572.

I do also have trouble exporting as a TIF with GIMP telling me tiff image plugin could not save image gimp, and also some other errors such as unable to read one line.

Do you have any ideas on how to fix this? Many thanks in advance!

Very difficult to give advice on those errors.

Best guess for the ImageMagick (IM) error is the image in some other place than the cmd terminal. I keep everything in a single folder to avoid using "path-to-file-name.ext" and run IM from there. Avoid spaces in file names as well. Then the no decode delegate might be IM looking at the CMYK.icc as an image.

Exporting the tiff from Gimp. That is not looking good. Indicates some issue with your Gimp file. Don't know.

HELP! Converting RGB to CMYK

...And a bit more.

How many of the 138 pages contain images ? If not too many then a cut and paste in Scribus can combine text and image.

In Gimp 2.10 export as a PDF as pages and every layer is a separate page. You can end up with 4 or 5 pages = the title page.

I can open that PDF in Scribus and get those pages. While text is not text, it is a vector image and that makes for 1) a smaller pdf 2) better quality.

..and forget that, at least for Windows. Totally unable to get Scribus and ghostscript (needed for a PDF) to open a multi-layer Gimp 2.10 exported PDF.

HELP! Converting RGB to CMYK

Sorry just seen this! Interesting so I could important the pdf images and text as separate pages? Sadly there is at least one photo image on every page, but it's something I can definitely look into. Thank you!

Would IM be able to convert RGB PDF to CMYK PDF perhaps?

..and forget that, at least for Windows. Totally unable to get Scribus and ghostscript (needed for a PDF) to open a multi-layer Gimp 2.10 exported PDF.

No way round that with Gimp, you have to merge the text with the image. Then text is no longer text.

rgb PDF to cmyk PDF using IM

Possible with the same proviso as before. Any text is converted to a graphic which also makes large PDF files.

The command is (and I hope that this time, this dumb, useless forum does not scramble it)

magick -density 300 rgb.pdf -evaluate Pow 0.454545 -colorspace CMYK cmyk.pdf

and if you find that the colours are too light

magick -density 300 rgb.pdf -evaluate Pow 2.2 -colorspace CMYK cmyk.pdf

The density commands are there otherwise IM will use 100 ppi (same as Gimp default PDF import) and you get a low quality fuzzy PDF.

収益と利益

所得
収益は、損益計算書の上部にあるため、最初の行と呼ばれることがよくあります。収益数は、コストが差し引かれる前に会社が受け取る収益です。

たとえば、靴の小売業者では、靴の販売から経費の会計処理までに稼ぐお金が収入です。会社が投資または子会社からの収入も持っている場合、この収入は収入とは見なされません。それは靴を売ることから来るのではありません。追加の収入源とさまざまな種類の費用は別々に会計処理されます。

利益 合計とも呼ばれ、損益計算書では利益は純利益と呼ばれます。損益計算書には、会社の業績を分析するために使用される利益の変動があります。 forex signals
ただし、トップライン(収益)とボトムライン(純利益)の間には他の収益率があります。 「利益」という用語は、粗利益および営業利益の文脈で生じる場合があります。これらは純利益に向けたステップです。

粗利益は、収入から売上原価(COGS)を差し引いたものであり、会社で販売された商品の生産に関連する直接コストです。この金額には、製品の製造に使用された材料費、および製品の製造に使用された直接人件費が含まれます。 forex trading signals
営業利益は、粗利益から、家賃、光熱費、給与など、事業の遂行に関連する他のすべての固定費および変動費を差し引いたものです。 外国為替シグナル無料
例:収入と収入
以下は、J。C。ペニーの2017年の損益計算書の数値と一部です。これらの数値は、2018年2月3日に終了した1万件の年次報告書で報告されました。

収益または総純売上高= 12.5億ドル 粗利益= 43.3億ドル(総収入12.50億ドル-売上原価81.7億ドル) 営業利益= 1億1,600万ドル(家賃、光熱費、給与など、ビジネスの遂行に関連する他のすべての固定費と変動費を除く) 利益または純利益= -1億1,600万米ドル。アメリカ(損失)1
主な違い
ほとんどの人が会社の利益を指すとき、それらは粗利益または営業利益を意味するのではなく、費用後の残高である純利益、または純利益を意味します。会社は利益を上げることができますが、純損失があります。 JKペニーは125億ドルの利益にもかかわらず、1億1600万ドルの損失を被ったことがわかります。 JKペニーの場合のように、損失は通常、負債または費用が利益を超えるときに発生します。 https://www.freeforex-signals.com/
特別な考慮事項
未収収益は未実現収益と同じです。未収収益は、顧客がまだ支払っていない商品またはサービスの提供のために会社が獲得した収益です。

たとえば、同社はすべての顧客にネット30ベースでウィジェットをそれぞれ5ドルで販売し、8月には10個のウィジェットを販売しています。彼は顧客に正味30単位で請求するため、会社の顧客は30日または9月30日に支払うだけで済みます。その結果、8月の収益は、会社が顧客から支払いを受け取るまでの未収収益と見なされます。 無料の外国為替シグナル
会計に関しては、同社は損益計算書の50ドルの収益を貸借対照表の資産として認識しています。会社が50ドルを集めると、損益計算書の現金勘定が増加し、未収収益勘定が減少し、損益計算書の50ドルは変更されません。

未収所得と不労所得を混同しないことが重要です。不労所得は、未収所得の反対と見なすことができます。 不労所得は、配達されなかった商品またはサービスに対して顧客が支払った金額です。会社が商品の前払いを要求する場合、会社は収益を未稼得として認識し、商品またはサービスが提供された期間中の期間まで損益計算書で収益を認識しません。
