Convertir une couleur CMYK en PMS Pantone sur Illustrator

Une amie m'a posé la question qui donne le titre de la discussion...
J'ai trouvé ceci: Edition>Modifier les couleurs>Redéfinir les couleurs avec paramètre prédéfini> 1 couleur, choisir la bibliotheque PMS de ton choix
Mais que disent les experts AI du forum?

Le plus simple est en effet d'utiliser l'outil de redéfinition des couleurs et de limiter à un catalogue de couleurs (voir lien de l'aide : Limiter à la bibliothèque)

Converting logo from CMYK to PMS SPOT

Hello everybody was wondering if you could lend a hand.
I have a logo that i wish to conver to pms spot colour as that is what the artwork requirement is, it is currently in CMYK.
I am currently using cs5.
Edit, Edit Colours,Recolour artwork, then i am going to colour books and choosing panatone solid coated.
Now it recolours 80% of the logo but leaves some panels as cmyk. I have come across this on different occasions before.
Is it somthing to do with clipping masks? I hope some Illustrator genius can point me in the right direction.
Cheers

As Monika said, your eps file contains raster images. They were most likely created when the original .ai file was saved as .eps which doesn't support all native .ai features. Recolor Artwork dosn't work with raster images. The best solution is if you have the original .ai file and use it to convert to Pantone colors there.
In case this is not an option you can convert the raster images in your file to grayscale and tell the printer to print the black plate with Pantone Black spot color.
To find the raster images in your .eps file, open the Links panel from the Window Menu and you will see all raster images listed. To isolate them, Shift click on the first and last on the list to highlight all of them and then from the menu of the Links panel choose Go To Link. This will select all raster image objects. Press Shift+Ctrl+Alt+3 to hide all others and now you have only the raster images displayed.
Also, to make it practical reduce the logo to 3 spot colors blue, red and black. You can use Windows > Separation Preview to check the color separations.

Convertir une image "Grayscale I16" en "RGB U64"

Bonjour,
je cherche depuis un petit moment sur tous les forums que je connais, et je ne trouve pas de réponse à mon besoin, à savoir convertir une image en niveaux de gris de 16 bits en RGB 64 bits. J'ai réussi à le faire en 32 bits, mais la dégradation est trop importante pour mes besoins.
Si vous avez une solution, je vous en serais reconnaissant.
Si ça peut vous aider, j'ai Labview 8.6 et NI Vision.
Merci d'avance

Si vous souhaitez, voici le VI que j'essaye de faire.
Il marche très bien en grayscale 8bits => RGB 32 bits, mais pas en Grayscale 16 bits => RGB 64 bits...
J'ai supprimé tout le traitement que j'effectue sur l'image pour que ce soit plus lisible. Comme j'effectue divers traitement suivant la couche de l'image (R,G,B), je suis obligé de passer par un Imaq ReplaceColorPlane.
Merci du temps que vous consacrez à mon problème.

Converting RGB to CMYK color

Hi All,
I have few BASIC Questions on converting RGB to CMYK in Photoshop and Illustrator. Hope could get some professional insights here.
1, Are all the DTG printers set only in CMYK color mode ?
2, If there is no difference after viewing RGB image with 'Gamaut Warning' (Photoshop), Does that mean I'll have the exact print result as monitor view ?
and Basically no need for CMYK conversion ?
3, Please list some the most effective way to convert RGB to CMYK, and keep the final CMYK color result as close as the RGB.
4, when I simply convert one RGB image to CMYK color, why Ps/AI don't allow me to save as PNG file ?
( I save the file as PDF, but I cannot edit this PDF using apple preview app )
5, compare Photoshop to Illustrator, which one result better final CMYK color image ?

Thanks for the detailed reply. Sure clear some of the doubts.
I just start to draw/design in Photoshop and illustrator, I save my files most as PNG, for a transparent background.
After I went to officework do the poster printing, I found the color of my print image are not as vivid as Mac preview.
To be precise, the poster I printed looks like has a very thin grey layer, it is not much noticeable, but it indeed lost some vivid color. As I want to print out my works and keep color as close exact as Mac preview, here is the issue of coverting RGB CMYK.
Please feel free to add for below:
1, Should I set color space in CMYK before drawing in PS/AI
2, in PS, I convert profile from PNG file to CMYK save as psd file, that psd file preview exactly same as PNG.
But when saved as PDF, the file preview a bit grey. Can someone explain this?
3, Now im thinking, since CMYK is all about printers, it really should be the profession in printing shop who shall check my image, and edit/convert to the right color space to fit their printers.

Having troubles converting RGB to CMYK

@Hi guys
I having massive issues with converting my business logo form RGB to CMYK. I need to place this logo on my business card ready for printing. I created the logo in RGB format to start of with, but it keeps coming out darker and abit grayscaled
once the conversation is set. Can anyone help me out with this issue, and if so, can you also provide the steps in how to resolve this issue for future references. Im using Adobe Photoshop CS5 for this execise. I can also provide the actual image attached below as the second image,.

These bright pink and purple colours are obviously way out of gamut so they convert badly to CMYK. Exactly how they convert depends on what colour profile you are using
It will probably be best to either rework the design using mixtures of cyan and magenta only or else use mixtures of Pantone colours.
The Pantone solution will only work for offset printing but is no use for a home printer.
Read up on colour management like Mylenium says and learn to think in terms of inks rather than screen colours.

Comment effacer à la gomme une couleur unique prélevée à la pipette ?

Je renouvelle la question postée précédemment sur le forum " photoshop first publish " en anglais ;
Comment sélectionner une couleur unique à effacer d'un calque en préservant le reste des couleurs par application du mode forme de l'outil gomme ?
Je voudrais pouvoir prélever une couleur unique à la pipette et l'effacer avec la gomme, pour par exemple améliorer la finition d'un contour objet séléctionné avec la baguette magique ou isolé avec la gomme magique.
Sur les exemples de démonstrations du site, cela serait par exemple de supprimer le rouge du phare en utilisant la gomme et la pipette ; ce qui doit être possible ( j'ai déjà vu cette applications sur des versions plus anciennes de ce genre de logiciels )
SVP merci
SVP Merci

Bonjour Ttro,
Je suis en vacances et c'est par hasard que je lis ta question. Je ne suis pas un spécialiste mais la sélection d'une couleur (plus ou moins étendue) peut se faire par la sélection d'une plage de couleurs .
Après ouverture de l'outil Plage de couleurs, tu peux utiliser la sélection des couleurs ou cliquer avec la pipette sur la couleur à effacer et jouer avec le curseur "Tolérance".
Une fois la couleur sélectionnée, tu peux l'effacer avec la touche retour ou la gomme.
Exemple sélection de la couleur rouge.
J'espère que ceci t'aidera.
Andres

Spècifier une couleur à une courbe d'un graphe

Bonjour,
J'ai réalisée un graphe à plusieurs courbes mais mon problème, j'arrive pas à distinguer entre ces courbes, je veux pour chaque courbe une couleur spècifique.
Quelqu'un aurait-il une réponse ? ou une astuce.
merci

Bonjour inesouira,
J'ai aussi un peu du mal à comprendre ce que tu veux faire. Si tu veux avoir plusieurs couleurs de courbe sur ton GraphXY, il te suffit de construire un tableau contenant les clusters de ton acquisition, les couleurs seront naturellement différentes (cf exempe). En revanche, si tu veux absolument réexécuter ton VI pour ajouter une courbe, je te conseil de regarder le fonctionnement d'une FGV, cela peut aussi être une solution.
En espérant avoir pu t'aider.

Can I change InDesign CC 2014 to default to cmyk mode for pantone colors instead of lab?

I work for a large corporation with close to 1000 sales people so we have a POD vendor who manages a website for the sales people to order our literature. Our colors were all great and now with InDesign CC 2014 using lab values instead of cmyk for pantones our colors are off. Is there a way to set InDesign CC 2014 to default to cmyk mode for pantones instead of lab?
Thanks,
Dave

so we have a POD vendor who manages a website for the sales people to order our literature.
The Pantone + Solid ink libraries only have one Lab definition. You can force a conversion to process CMYK via Ink Manger and the converted output values will depend on the document's CMYK profile.
If you prefer a single, device dependent CMYK definition for a solid ink simulation, you now have to use the Pantone + Bridge library—those colors are defined as process CMYK—or you can go back to the legacy solid library

J'espère que tout cela fait sens. Je vais donner à ceci un essai en utilisant Google Translate.
On dirait que vous voulez supprimer un objet qui est d'une certaine couleur. Vous ne voulez pas utiliser l'outil Gomme. C'est destructeur et facile d'aller en arrière et corriger votre travail. Utilisez un masque de calque à la place.
Faites une sélection soit avec la baguette magique ou l'outil de sélection rapide. Ensuite, utilisez affiner bord de nettoyer la sélection. Sélectionnez> Améliorer le contour. Enfin, avec la sélection active créer le masque de calque pour que couche. Choisissez Calque> Masque de fusion> Masquer la sélection.
Les noms de commande réels peuvent ne pas correspondre en raison de la traduction google.

Converting Images to CMYK for Print Publication

When in my workflow should I be converting images to CMYK for print publication?
Currently, I shoot RAW photographs with my DSLR in Adobe RGB, import the images into Photoshop for manipulation and then convert the final, sized image to CMYK before placing it in my Indesign document. Before going to print, I convert my files to PDF using the [PDF/X-1a:2001] preset. I use a calibrated system with a profile set for my monitor.
Since many of my pictures have shades of green, I'm often disappointed with the conversion to CMYK because I lose saturation and brightness. Am I doing anything wrong? Is there a better way of preserving the quality of colour in my images when going to a commercial printer?

To see in InDesign what color shifts will occur, use View=>Proof Colors.
I would also recommend View=>Overprint Preview.
Yes there are color shifts when converting RGB to CMYK, but those are due to the fact that the gamut of CMYK is significantly less than AdobeRGB or even sRGB. The same color shifts going to CMYK will occur whether you convert the image in Photoshop or in InDesign during PDF export or at the RIP.
Keeping the color in ICC color managed RGB has the advantage that last minute changes can be made as to what CMYK printing conditions are used, i.e. all CMYK is not the same. Furthermore, if you convert RGB to CMYK early in the workflow, you lose the ability to maintain the color gamut for display of the PDF as well as for printing to high fidelity color devices, i.e., offset or digital (especially inkjet) devices that have extra colorants such as light cyan, light magenta, orange, and/or green to dramatically expand the gamut. Once you lose the gamut in your imagery via conversion to CMYK, you can't go back.

Hi,
I am having similar problems. I have read somewhere that png format can not handle CMYK colorspace anyway, which I find odd (and plainly stupid IM(NS)HO) which would mean that converting to RGB and therefore using profiles is mandatory.
May be you should check if the internal format of the png files claims it is RGB or CMYK (using ImageMagick's "identify" command for example).

Hi, cannot convert RGB to CMYK...

I cannot find such an option in the Elements? Can anyone help how can I convert the files to CMYK from RGB using this tool...
Thanks
ansu

Elements can't convert RGB to CMYK. You'd need the full Photoshop.
Otherwise you can google 'RGB to CMYK' conversion to find online or software tools that can do that.
The real question is why do you need CMYK. If it's a request from a printer shop, it's their job and responsibility to do the conversion, since such a conversion can only be properly done when you know the specificity of your printing tools, inks and papers.

Color converting RGB to CMYK mode???

Is it possible to convert RGB to CMYK color mode in Elements 10?

No, not really. If you google around, Richard Lynch had a sort of workaround for this for very early versions of PSE that could possibly be adapted for current use, but a proper CMYK conversion is much more complex, even with the proper tools, than going from sRGB to Adobe RGB, for example.
If you have a mac you can do a mode conversion in Preview, but you may not like what you get from the print shop using that method.

Sorry, but this is one of the very hard lines that Adobe draws between PS and PSE. You simply can't do it in PSE, because they want you to buy PS for that.
