Curve Recipes

What is a Curve Recipe

A curve Recipe consists of ingredients, which are the parameters you can use building a curve Recipe:

Resolution
Dotshape
Ruling
Separation
Angle

One curve Recipe consists of a combination of one or more of these ingredients.

Note: The parameters Separation and Angle are exclusive, as combining a separation name and an angle in the same rule can lead to ambiguity.

Create a curve Recipe

To create a curve Recipe, follow these steps:

Go to RIP > CURVES and select a curve Profile for which you want to create a curve Recipe.
Select .
Select and specify the ingredients you want to use to build the curve Recipe.
Select OK.
Define the Curve Details for the curve that is assigned to the Recipe.

Treebased rule view

By adding curve Recipes, you create a treebased rule view in the user interface:

There is always a Default Recipe defined. You cannot delete or rename this Recipe.

Each combination of predefined ingredients makes sure the RIP uses a specific curve during the RIP process.

If you create a new curve Recipe, the system automatically selects the biggest subset to position the Recipe.

If one ingredient is defined in the selected recipe, the new Recipe is added to the selected Recipe.

Example

In the above image example, you have created a separate curve for the following situation: 2540 dpi - HXM - 133 lpi. Consequently, you have to create a Recipe with ingredients for 2540 dpi - HXM - 133 lpi. If you do so, the Recipe will be added to the 2540 dpi - HXM branch:

Rule based system

Curve Recipes follow a rule based system that determines which curve is used during RIP phase. The RIP looks for the Recipe that best matches with the attributes of the file, starting from the top. When a match is found on top level branch, the sub branches are examined to find an exact match. If no exact match is found, the best matching Recipe on parent level will be used. If the Recipes on parent level do not match either, the Default Recipe is used.

Example

In this example, there are two top level branches:

One for a resolution of 5080 dpi.
One for a resolution of 2540 dpi.

Each resolution branch has children with sub branches that are defined by the following ingredients: dotshapes with screen rulings, and in one case also separations. All these ingredient combinations have an assigned curve. This ruleset with an assiged curve is the Recipe. In the example, 20 Recipes are defined, including the Default.

During the RIP phase, the RIP looks for the Recipe that best matches the RIP settings. The curve that is assigned to the Recipe is used to RIP the file. When looking for the best matching Recipe, the system starts at the top of the tree and works its way down, until the best match is found. If no match is found, the Default Recipe is used.


RIP settings¹	Recipe	Info
2540 dpi Round 150 lpi	A	Recipe A matches all the file attributes.
2540 dpi HXM 200 lpi	B	There is no Recipe that matches all the file attributes of 2540 dpi - HXM - 200 lpi. The best match, starting from the top, is 2540 dpi - HXM.
2540 dpi Round 105 lpi Orange	C	There is no Recipe that matches all the file attributes of 2540 dpi - Round - 105 lpi - Orange. The best match, starting from the top, is 2540 dpi - Round - 105 lpi.
5080 dpi HXM 120 lpi	D	There is no Recipe that matches all the file attributes of 5080 dpi - HXM - 120 lpi. The best match, starting from the top, is 5080 dpi - HXM.
4800 dpi HXM 175 lpi	E	There is no Recipe that matches all the file attributes of 4800 dpi - HXM - 175 lpi. The best match, starting from the top, is the Default Recipe.

The RIP looks for the Recipe that best matches with the attributes of the file, starting from the top and working its way down. Therefore, the order of the Recipes is very important. To reorder the Recipes, or to change the position of a Recipe, drag and drop the Recipe to the desired position. On the left side, a small black arrow shows if the Recipe will be added before, after or in another Recipe after dropping the Recipe. If the drop is accepted, a green sign is displayed. If the drop is rejected, a red cross is displayed.

Note: When a section of the incoming file has Object Based screening attached to it, the screening parameters applied to this object determines the curve that will be applied for this object. This is only the case if the object based has no curve applied to it, or if the curve is an identity curve. In all other cases, the curve applied to the object will be the result of evaluating the object based screening parameters.
