  1. In version 30.5.1, Illustrator stopped writing color settings to ACEConfigCache2.lst, the file used for color settings synchronization.

    Photoshop, Illustrator, InDesign, Acrobat, and Bridge use ~/Library/Preferences/Adobe/Color/ACEConfigCache2.lst to store and synchronize their active color settings preset names.

    Up through Illustrator 30.5, Illustrator correctly wrote its own color settings information to this file. However, starting with version 30.5.1, it not only stops writing its color settings entry, but also removes the Illustrator 2026 entry from the file entirely.

    Illustrator 30.5.1 still appears to read color settings written by Bridge and can apply the corresponding preset correctly. However, given that it no longer maintains its own entry in ACEConfigCache2.lst, I would like to ask whether this behavior is intentional or if…

  2. 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…

  4. 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。

  5. 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?

  6. 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.

  7. The preview is incorrect because some images are missing

    Ever since at least Illustrator version 29.8.5, I've been having preview issues with linked images. Some images are missing from my preview.

    I tested it in Illustrator 30.3, and the problem persists.

  8. 「選択範囲を書き出し」でSVGを書き出す際、無関係なPNG画像が同時に出力される

    Illustrator 2024で「選択範囲を書き出し」からSVGを書き出す際、本来選択しているオブジェクトではなく、無関係なPNG画像や別のSVGデータが出力されます。

    問題のPNG画像は、
    ・アートボード上に存在しない
    ・現在開いているファイル内にも存在しない
    ・2年ほど前に使用した記憶のある画像
    ・アセット書き出しパネルにも表示されない

    という状態です。

    また、
    ・新規ファイルを作成しても再発する
    ・通常のPNG書き出しでは発生しない
    ・「選択範囲を書き出し」→SVGの場合のみ発生する

    ことを確認しています。

    さらに、出力されたSVGには、現在選択しているオブジェクト以外の無関係な内容も含まれており、意図した内容だけを書き出すことができません。

  10. Memory error after exporting in EPS (ID -108)

    On Illustrator 30.6 every time I export a multipage file to eps format, every artboard as a single file, the file exported are ok, but if I return to the original AI file to save the changes I receive a memory error (see the screenshot) then is not possible to save the AI file no more, and I have to use the SAVE AS command to save a new AI document from the original.
    This bug appeared in Illustrator 30.6

  11. Export for Screens Inaccurate on Large-Size Canvas

    The export for screens, scaling by width option does not always export at the right size. For example, I will input 2000 pixels, but the exported images will be 20,000 pixels. Sometimes, it does output 2000 pixels as desired. I believe the pattern may be whether the file is a large-sized canvas or not, the large-size canvas being the inaccurate export. For the time, I have been using "200" to get 2,000 pixels. However, this feature is essential for exporting mockups of large-format prints as the true size is too large for sharing. Usually I am exporting JPG. I am…

  12. Illustrator repeatedly gets stuck saving causing a forced restart and loss of document

    Illustrator repeatedly gets stuck saving almost every document that has any complexity. It will not finish it's save and requires a force quit/restart. It will also not autosave any document changes made before the error, so every time it happens it requires the file to be made from scratch. This has become so persistent in my files that I can no longer use illustrator.

  14. Vector shape out of place after saving as SVG

    This is about the version 30.6. After saving the illustration as SVG, some elements got out of place.
    As you'll see on the attachment, the black elements should be aligned to the road lanes.
    I had to down grade to version 30.1 (desktop) to fix it.

  16. 書き出し時の同名ファイルの警告が出ない

    png、jpgでの書き出しのとき、すでに同じファイル名がある場合に警告メッセージが出なくなり、そのまま上書きされてしまいます。
    上書きの警告メッセージの出し方、またはそれ自体が無くなったのであれば、改善していただきたいです。ver30.5.1です。
    ちなみに、ネットでいろいろ調べると「環境設定」に「書き出し」があるとか出てくるのですが、その書き出し自体の項目も無くなっています。

  17. 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.

  18. Illustrator not letting me save my files or very slow

    Illustrator keeps lagging on saving sometimes not responsive and not letting me quit illustrator.
    Did not use to happen about a month ago.

    Illustrator 30.3
    Macbook Pro M1 Max
    Sonoma 14.8.5 (23J423)

    Admittedly we run our server on Dropbox, but even still it was not a problem about 1 month ago.

    Please don’t ask me to to save files locally as that is not a viable solution.

    Saving on dropbox was working fine without issue a few months ago, now all of sudden it is lagging for 10 mins a file that used to take 1min to save sometimes not…

  19. 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…

  20. 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…
