EXPORTATION JPEG GESTION DES COULEURS

[guillaumes83311920]

Bonjour

L'exportation jpeg à partir d'Indesign ne tient pas compte des pseudonimes du gestionnaire des couleurs.

C'est très important pour avoir des visuels conformes aux résultats souhaités.

Cordialement

Acrobat has had the ability to use PDF layers for some time, as does the free Adobe Reader. If a PDF has layers, the layer icon should appear on the left side of the Acrobat window, it looks like a stack of papers. By clicking the eyeball icon, the layers can be turned on or off. This is a common method of producing print and proof ready PDFs. You can set the layers as you like and export the PDF to an image (jpeg). I believe the ink opacity setting should not change when you export a layered PDF from InDesign. (select Create Acrobat layers in the export dialog).

I should also mention you need to create your layers in InDesign. If you are placing a layered object (from Illustrator for example) you can copy it to each layer and use InDesign Object> Layer options to correctly set the layer visibility.

Hi Luke, I’m not sure I’m completely following how the spot color’s ink Type would be used in @guillaumes83311920 ’s workflow, but I don’t think the InDesign spot color’s ink Type gets saved with the PDF:

[Luke Jennings3]

Yes, you are correct. I'm a bit surprised the PDF does not retain that info. I know ink types are used in the Esko Automation engine workflow, although ink the properties can be set up in advance (based on spot color name). Esko uses Normal, Opaque, Varnish & Technical (AKA dieline).

Ink Types seem like a trapping property, and the InDesign document Trap preset don’t make it to the PDF either.

Ce qui est très dangereux, quand on a affaire à un fichier complexe et que l'on traite plusieurs dossiers en même temps.

Unchecking the script’s Simulate Overprint should solve the overprint problem. Here I have the text with PANTONE 872 set to OverPrint with Overprint Preview on and the JPEG exports with the text knocking out without setting the Overprint Attribute.

Merci

Cela ne fonctionne pas (voir pièce jointe erreur script)

l'aperçu des séparations ne tiens pas compte des encres opaques, l'exportation JPEG non plus.

Seraît t'il possible que le script tiennes compte du type d'encre utilisée pour chaque encres ?

(pièce jointe : capture encre opaque)

[rob day]

That‘s a language problem–the script is looking for the english version of the "[High Resolution]" flattener preset. Try this version:

If you want colors you have set to Overprint in the Attributes panel to export as not overprinting, you’ll have to uncheck Simulate Overprint.

Le bug est corrigé merci,

Pouvez-vous, intervenir sur l'option "TYPE OPAQUE" pour chaque objet comme simulé en pièce jointe ?

(Uniquement pour l'exportation JPEG)

merci

[rob day]

il n'y a pas de 872, seulement de l'OR A CHAUD

The PANTONE .ACB libraries are no longer being updated in the CC apps. Try the New Pantone Connect panel (Window>Find Extensions on Exchange).

Vous avez mal compris, c'est un problème de traduction, désolé

No, the ink manager Type has some affect on  InDesign’s built-in trapping when you print separations with trapping turned on, but ink Type does not have an affect on the displayed appearance of a spot color. 

There is not accurate color management for spot color tints and overprints—full color management depends on device color profiles and are limited to process RGB and CMYK.

Pantone’s Solid Ink Spot color libraries are defined with measured Lab values, and the soft proof of the 100% value on white paper is reasonably accurate if you are viewing on a calibrated and profiled display. Tints, overprints, and mixed inks are not necessarily accurate, because there are no spot color profiles that will take into account the halftone dot gain and the ink’s transparency. With process CMYK, a CMYK .icc profile can capture those properties from a press profile target proof.

Merci pour votre réponse

Ce n'est pas une couleur exacte que je recherche, cje voudrais que l'exportation jpeg ne tienne pas compte de la surimpression seulement sur les objets qui ont une teinte de type opaque.

Comme en pièce jointe.

It would not be easy. The script would have to check the fill and stroke of every object and character in the document, change the overprint setting depending on the ink type, make the export, and reset everything back to its original state.

I’m wondering if exporting the InDesign layers to a layered Photoshop file would be better. I posted a Photoshop Layer script awhile back and you can get the JS and AS versions along with usage details here:

https://community.adobe.com/t5/indesign/indesign-layers-to-photoshop-js-version/td-p/11484245?page=1

The script exports InDesign layers to corresponding Photoshop layers. Here I have the background fill, text and stroked oval on separate layers:

The scripted Photoshop file:

The Color layer set to Multiply:

Bonjour

je suis désolé pour ma réponse tardive, j'ai énormement de travail en ce moment et je n'ai que peux de temps disponible.

Votre solution est très intéressante, mais ne peux fonctionner que si la mise en page se fait dans Indesign, mais pas avec un fichier lié (Illustrator ou pdf).

J'ai trouvé plusieurs problèmes a votre script

- aucunes informations de surimpression n'est prise en compte

- les calques masqués sont traités de la même manière que les calques actifs.(pièce jointe)

Le script export jpg est plus proche de ce que je souhaite, il faudrait juste ignorer les informations de surimpression des objets (contour et fond) utilisant une teinte de type "opaque".

Cordialement

If you want to export with Overprints make sure you check Simulate Overprint, with it checked the JPEG should match InDesign‘s Overprint Preview:

With it unchecked:

The "GREEN GHOST" layer exports when it is visible:

[rob day]

Also, if you are still getting the error with Sumulate Overprint checked, make sure you get the latest version:

https://shared-assets.adobe.com/link/61c31413-4654-4222-5535-bbeedbbacc37

I don’t think there is a practical way of handling different spot color ink Types. The Photoshop layer script I linked to above would let you simulate different overprints on separate layers, but you would need to edit the Photoshop layered file.

toutes mes excuses, je n'ai pas l'habitude des forums

je vous avez répondu sur :

le script Export Jpeg fonctionne très bien, merci !!!

J'aurais aimé qu'il soit amélioré avec la prise en compte des encres opaques pour une visualisation plus juste.

En vous remerciant très sincèrement pour tout ce que vous faite.

[rob day]

Sorry, my fault—I thought you were still questioning the JPEG Export script. 

[rob day]

 but can only work if the layout is done in Indesign, but not with a linked file (Illustrator or pdf).

An Illustrator .AI or PDF placed in InDesign should export:
