  1. Compatibility Issue in Illustrator v30.2 - PostScript Error <a1a1>

    Critical Update: This issue is not limited to specific files. Every single file saved or exported from version 30.2 encounters the same <a1a1> error, even when the document contains only a simple primitive shape (e.g., a single rectangle). This indicates a systemic failure in the PostScript generation engine of the v30.2 build on my system.

    Description
    Since updating to Adobe Illustrator v30.2, I have encountered a critical compatibility issue. Even when saving files for lower versions (Legacy formats), recipients are unable to open them. The files trigger a specific PostScript error regardless of how simple the vector data is. This…

  3. Acrobat layers duplicate excessively in AI file’s compatible PDF

    Illustrator 2025 (29.8.2)

    When “Save in Background” is enabled, the Acrobat layers in the compatible PDF within AI files duplicate according to the number of artboards. For example, when there are 10 artboards and 2 layers, there should be 2 Acrobat layers, but instead 20 layers are generated.


    aiファイルの互換PDFでAcrobatレイヤーが過剰に複製される

    「バックグラウンドで保存」が有効な場合、AIファイル内の互換PDFにおけるAcrobatレイヤーがアートボードの数に応じて複製されます。例えば、アートボードが10個、レイヤーが2個ある場合、Acrobatレイヤーは2個であるべきところ、実際には20個のレイヤーが生成されます。

  4. Thumbnails glitching when saved

    Randomly, when files and thumbnails are saved out of Illustrator, the resulting thumbnails are glitched in a variety of ways. This glitch is present in the preview in the Finder window, but upon opening the file again, the glitch is not present. This is not from appearances or overprint being applied to artwork elements, as we are familiar with the issues those settings present in a print production environment, and this is a separate issue.

    • Running on a MacBook Pro, 2021, running Sequoia 15.0.
    • Using Illustrator 30.0.
    • The issue occurs when Illustrator saves a file or thumbnail, randomly, without any…

    Everyone - we want some more information about this issue.

    Is any export (PNG) done from Illustrator for any such (glitched preview) files showing the same thumbnail issue or not?

    Or, is the issue happening only with the thumbnail of the file as seen in the Mac / Win folder preview or while placing into another application?

  5. Image Map URL Links Disappear in PDF Export

    Issue occurs in Illustrator 2025 (29.6) and later versions

    Description:
    URL links configured through the Attributes panel’s Image Map feature are not preserved in exported PDFs, despite enabling the “Preserve Hyperlinks” option in PDF export settings.

    Steps to Reproduce:
    1. Create a new document
    2. Create an object (e.g., rectangle, text, etc.)
    3. Select the object and enter a URL in the Attributes panel → Image Map
    4. Create a new layer above the current layer
    5. Export as PDF with “Preserve Hyperlinks” enabled in export settings
    6. Open the exported PDF in Adobe Acrobat

    Expected Result:
    URL links should…

  7. PDF/X-4で書き出す際にダウンサンプルされる

    macOS14.7.2/Imac27inch i5/32GB mem/1TB ssd
    Illustrator ver29.5

    再現手順
    1.800ppiのモノクロ2開帳の画像をドキュメントに原寸で配置する。
    2.ファイル→コピーを保存を実行、PDF形式を選択し次のダイアログでプリセット「PDF/X-4:2008(日本)」を選択して保存する。
    3.PDFを開いて配置した画像を調べると300ppiにダウンサンプルされている。

    期待する結果
    800ppiのままダウンサンプルされずに保存される。

    実際の結果
    配置したビットマップ画像は300ppiにダウンサンプルされる。

    このプリセットでは実行解像度が1800ppiを超えた際に1200ppiにダウンサンプルされるように設定されている。配置状態で800ppiの画像はダウンサンプルの条件に当てはまらない為ダウンサンプルされてはいけない。
    また、300ppiという数値はモノクロビットマップ画像を取り扱うには致命的に低い解像度と言える。

    回避方法
    ビルトインのPDF/X-4プリセットは利用せず、同等のプリセットを自身で作成して利用する。その他、プリプレス関連メーカーが配布するPDF/X-4プリセットを利用しても良い。

    EN
    Step to reproduce
    1. Place an 800ppi monochrome bitmap image in the document in its original size.
    2. Select File→Save a copy, choose PDF format, and in the next dialog, select the preset "PDF/X-4:2008 (日本)" and save the file.
    3. Open the PDF file in Acrobat and check the placed image to find that it has been downsampled to 300ppi.

    Expected result
    The image is saved without being downsampled to 800ppi.

    Actual result
    The placed bitmap image is downsampled to 300ppi.

  8. Exporting To SVG Format

    Illustrator 30.2.1 has a consistent SVG exporting bug. I created some images containing gradients. When I export to SVG the first time, AI will create a correct SVG file. However, subsequent exports, AI will leave out all gradients. If I close the file and reopen it, the cycle repeats.

  9. Illustrator 29.8.2 saved .ai-file containing outdated pdf-version

    We have a user that several times has encountered a serious bug with saving documents. Currently on version 29.8.2 (the latest available for us in the CC desktop app as of today). Windows 11.

    Attached is an AI file showing the bug. Try opening it in e.g. Photoshop and Illustrator. You get very different versions.

    It is a "PDF compatible file" saved from Illustrator, so it contains a PDF version for other apps to use, but this embedded PDF version shows an older version of the illustrator file (so opening it in Illustrator looks fine, but when using it in…

  10. "Open" window loads blank and duplicates

    Operating System:
    macOS 15 Tahoe – MacBook Pro M1 Pro, 32 GB RAM (Apple Silicon)

    Illustrator Version:
    Adobe Illustrator 30.0 (desktop)

    Issue Description

    When I try to open files using File > Open… or the shortcut Cmd + O, the “Open” dialog window does not appear immediately. Sometimes it takes several seconds, and other times it takes minutes before it shows up.

    Because of the delay, if I press Cmd+O again or click File > Open repeatedly, Illustrator eventually opens multiple overlapping blank windows. These windows appear with a dark/empty content area and no file information loaded.
    They also…

  12. Unknown Error when saving

    Windows - Adobe Illustrator 2026

    When saving files for a proof - Press Quality, no editing, password, low resolution printing, no changes, no enabling copying of text - this error comes up on the first attempt every time.

    If I save it a second time, this error doesn't happen. I wasn't receiving this issue until I updated to 30.2.1, but it was rare. Now that I've updated to 30.3 it became every time I saved a new file for the first time. As much as I want the turntable feature, I'm going to have to use 30.1 again until the…

  13. PDF export without color conversion converts RGB images to CMYK

    This is a bug that occurs in Illustrator 2025 (29.2.1) and later.

    When an RGB image is placed as a linked file in a CMYK document, it gets converted to CMYK upon PDF export, even if "No Color Conversion" is selected. In Illustrator 2025 (29.2.0) and earlier, the image remained in RGB.

    This bug affects only PNG and JPG files. Other formats, such as PSD, remain in RGB.

    Steps to Reproduce

    1. Create a new CMYK document.
    2. Place an RGB image (PNG or JPG) as a linked file (do not embed).
    3. Export the document as a PDF with "No Color Conversion"…

  14. Export for Screens scale dropdown doesn't work

    In the Export for Screens dialogue, the dropdown does not change the scale entered in the box. For example: box says 0.25x. I choose 1x in the dropdown, 1x is checked in the dropdown, but the box still says 0.25x and the export will be 0.25x.

    Typing the scale in the box works.

  15. Cannot Save as New File in v30

    Using the latest version of Adobe Illustrator (2026 version?)

    Trying to "save as new" but the save window does not load completely and then button shapes inside disappear and remains in this state. The only thing you can do is close the box.

  16. Saving in older illustrator format scales 10 times down

    When saving a file in an older illustrator format, now the file appears 10 times smaller. As a signmaker working with sign software that doesn't accept newer ai or eps files this is VERY MUCH unwanted. I can scale it back to 100% in my sign making software but only manual. Not by alttering the comma in the scaling. This isn't accuracy I often need. Please undo this downscaling. Me, and a lot of colleagues, work for decades this way.

  17. No se puede abrir el archivo. "No es posible acceder al archivo con la cuenta que has iniciado sesión".

    Eso dice al intentar abrir un archivo. Pero la cuenta con la que estoy intentando abrirlos es la misma cuenta con la que los creé. Eso no me pasaba hasta que se actualizó a la versión 30.3 el Illustrator. Necesito ayuda, por favor. No abrir absolutamente ningún archivo, en todos me aparece la misma leyenda: "No se puede abrir el archivo. No es posible acceder al archivo con la cuenta que has iniciado sesión. Ponte en contacto con el propietario para consultar más detalles." Pero yo soy la propietaria, ayuda por favor.

  18. Problem mit verknüpften Bildern in platzierten Illustrator-Dateien seit Update 30.2.1

    Seit dem Update von Adobe Illustrator auf Version 30.2.1 tritt ein Problem im Umgang mit platzierten Verknüpfungen auf, das zuvor nicht vorhanden war.

    Beschreibung des Problems:

    Wenn in einer Illustrator-Datei ein Bild platziert und als Verknüpfung (nicht eingebettet) eingefügt wird und diese Illustrator-Datei anschließend wiederum in eine zweite Illustrator-Datei platziert oder eingebettet wird, erscheint das verknüpfte Bild aus der ersten Datei in der zweiten Datei nicht mehr.

    Das Bildfeld bleibt leer, obwohl die Verknüpfung korrekt vorhanden ist.

    Erwartetes Verhalten (wie in früheren Versionen):
    In vorherigen Illustrator-Versionen wurden verknüpfte Bilder innerhalb einer platzierten .ai-Datei korrekt angezeigt, auch wenn diese Datei in…

  20. Phantom objects in Finder Preview and when imported into Photoshop

    I'm on MacOS. When previewing an .ai file in Finder, there will often times be phantom objects visible in Finder Preview. These objects are always duplicates of whatever is actually visible on the artboard-- usually it's a phantom object in the position the object was in the last time I saved the file. When I open the .ai file in Illustrator, those objects do not exist. The objects are not hidden; they are not on some other layer. This is particularly problematic because those phantom objects are still there if I open the .ai file in Photoshop. If I add…
