Page size error and wrong PPI
I have a big problem.
I want to the print an A4 template (pixel size must be 2480 pixels x 3508 pixels print resolution), but if I open the template I see always this size 595 pixels x 842 pixels (screen resolution).
I chance the PPI to 300 in Rasterize menu, but the page size remains the same.
I hope you can help me.

This is not how it works in Adobe system.
Changing the resolution value in both Object > Rasterize or in Effect > Document Raster Effects Settings doesn’t not affect the implied resolution of a document — these are about the resolution used to rasterize a selected art and the resolution used to generate raster effects.The resolution of the document while creating a document does not exists in Illustrator.
While in Photoshop you can specify the resolution, it’s possible because Photoshop basically rasterizes a document to the set parameters before it gets created. Resolution in Photoshop is just a coefficient, and the only true unit there is pixel.
Illustrator deals with points instead — it’s what the PostScript language is built upon.
While pixel IS Point in Adobe universe, the 'point' is a real-world value — 1/72 of an inch. And since all units are defined by each other (like in the real world), size in millimeters equals the exact number of points.A4 is 210×297 mm. Point is 1/72 of an inch. Inch IS 25.4 mm exactly, according to the International System of Units.
So 210×297 mm IS 595.276×841.89 points (close to). This is what the template is, this is what the 72 PPI means.
Practically it means if you need to create a 2480×3508 pixels (points!) document in Illustrator — use these dimensions specifically. And if you then change units to 'millimeters' — it won’t be an A4. What you can do instead, is to create an A4 document and then export it into a raster image using 300 ppi resolution.
