What is the web growth feature? The Web Growth feature lets Prinergy Evo software digitally compensate for press distortion. On a web press, the main direction of growth is across the web. On a sheet-fed or flexographic press, you may find more significant growth in the direction of paper travel. The web growth compensation mechanism in Prinergy Evo software can simultaneously compensate for growth both across and along the web or sheet.
Which files does the feature use? The Web Growth feature uses the following files:
The DTD file contains the definitions and comments that describe the XML tags in the profile file. The profile file uses the DTD file; you do not use the DTD file. You can either store the profile file and the DTD file in the same folder , or store the files in separate folders and include the location of the DTD file in the profile file. A profile file describes press distortions for a specific press, paper stock, humidity, ink coverage, and other factors. You create one or more profile files using a text editor after you've measured your distortions on press. You enter the measured distortions in the profile file. You can then apply a profile file to each input file. Prinergy Evo software uses the profile to alter the image for each plate for a specific press and paper combination. Following There are several defaults to consider when you're setting up your web growth profile:
The tower-color file is a text file that specifies the names of the color separations in a file and the number of the press color tower running each color. What does the feature compensate for? The Web Growth feature lets you compensate for linear scaling (bidirectional if desired) or non-linear scaling. What is the webgrowth exclude margin feature? The Web Growth Exclude Margin feature allows you to specify a margin along one or more edges of the plate where web growth scaling will not be applied. When you exclude margins, two regions on the plate are created: the margins you have excluded and the rest of the plate. The area around the edge of the plate is imaged with no web growth specified, while the inside area of the plate has web growth scaling applied. One use of this feature could be not to add web growth scaling to the left and right sides of a plate, which contain control marks. An automated bender could scan these marks and determine how much to bend the plate for a certain press. If you applied web growth to the left and right sides of the plate, misregistration would occur. Things to consider:

En quoi consiste l'option d'étirement de la bande ?
Quels sont les fichiers utilisés par cette option ?
Le fichier DTD contient les définitions et les commentaires décrivant les balises XML dans le fichier de profil. C'est le fichier de profil qui utilise le fichier DTD ; vous ne l'utilisez pas. Vous avez la possibilité de stocker le fichier de profil et le fichier DTD dans le même dossier, ou bien de stocker les fichiers dans des dossiers séparés et d'inclure l'emplacement du fichier DTD dans le fichier de profil.
Le fichier tour-couleur est un fichier texte qui établit une correspondance entre les sélections de couleurs d'un fichier et les numéros des tours censées les imprimer.

Cos'è l'espansione della bobina?
Quali sono i file utilizzati da questa funzione?
Il file DTD contiene le definizioni e i commenti che descrivono i tag XML nel file di profilo. Il file DTD viene utilizzato dal file di profilo, ma non dall'utente. È possibile memorizzare il file di profilo e il file DTD nella stessa cartella, oppure memorizzare i file in cartelle separate e includere la posizione del file DTD in un file di profilo.
Il file dei colori dell'unità di stampa è un file di testo che specifica il nome delle selezioni di colore in un file e il numero delle unità di stampa che stampano tali colori.
