Question

Überdruckvorschau macht Illustrator extrem langsam

Hallo zusammen,

ich benutze Illustrator 25.4.1 auf einem iMac mit macOS Big Sur 11.6 und habe das Problem, dass ich in der Überdruckvorschau nicht flüssig arbeiten kann. Sobald die Ansicht aktiviert ist, "hakt" das Verschieben mit dem Hand-Werkzeug und das Scrollen extrem. Hatte jemand von euch dieses Problem auch und konnte es irgendwie lösen? In InDesign habe ich ein ähnliches Verhalten bemerkt, aber es ist nicht ganz so extrem wie in Illustrator.

 

Kurz noch die Eckdaten zum iMac:
3,4 GHz Quad-Core Intel Core i5

24 GB 2400 MHz DDR4

Radeon Pro 570 4 GB

2,12 TB Fusion Drive

Technisch gesehen sollte das doch ausreichend sein, oder?

 

Danke und viele Grüße

Instead of setting a color to Overprint, try Darken blend mode.

It should have the same effect, and does not need Overprint Preview to show the result.

Spot colors are separated and the result is shown in PDF viewers that cannot show Overprint.

And it probably speeds up the display because the GPU can be used.

Hi Ton,

 

thank you for your response and suggested solution. Unfortunately Illustrator works that bad even if there are no overprinting colors. Furthermore we get Illustrator files from our clients that we have to edit. Therefore, we have little influence on how the colors are applied. Even if we change overpriting colors to blend modes then, the overprint view helps us to identify overprint and to "navigate" through the artwork with e. g. the hand tool. Since I never had problems with the overprint preview on the Windows PC, I wondered why it was different on the iMac.

Yes, I understand that you don't have control over customer files.

I am afraid that only Adobe staff/support can help by looking at your iMac.

    Hi there,

     

    Sorry about the trouble. In Overprint view, Illustrator switches to CPU view. Thus, there is a minimal noticeable lag in less complex art, and it will lag heavily If your artwork is complex. If that is not the case, please share a small video demonstrating the issue, it will be really helpful for us to understand, and we can assist you accordingly.

     

    Will be looking forward to your response.

     

    Regards,

    Hi Anshul,

     

    thank you very much for your answer. I made two videos: one with the iMac (Intel Core i5), one with a Windows PC (Intel Core i7). Even without complex artwork and no overprinting elements, Illustrator behaves very poorly on the iMac compared to the PC in overprint preview. But the processor of the iMac should be sufficient as well?

     

    Thanks for your help and best regards

    Thank you for sharing the details and video clips. iMac should be able to handle it, but overprint is highly dependent on CPU usage. I tested on the i7 Macbook pro, one generation older than your iMac, and it doesn't lag in comparison to your video clip. Additionally, fusion drives are 50% slower than basic NVME SSD, which MacBooks have been using since 2016, and newer iMacs. Could you please tell me the specs of your Windows PC? Also, I would suggest you to create a new user account and install Illustrator only. Then check how overprint works there.
