  1. 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.

  2. We request that function key conversion be re-enabled for Japanese input.

    Due to the latest update release, the conversion shortcuts using function keys during Japanese input have become unavailable. Please restore them so they can be used again.

    Conversion shortcut details:
    F6 → Hiragana
    F7 → Katakana
    F8 → Half-width Roman characters
    F9 → Full-width Roman characters

    In Japan, conversion shortcuts using function keys are commonly used.
    Previously, I could use those keys for Japanese input conversion without having to delete the corresponding Illustrator shortcut settings. However, in the latest version, even deleting the settings doesn't work, which is inconvenient.

  3. Suffix still gets added when an image is exported even though the option to add it is disabled

    While exporting a AI file to, for example JPG, the checkbox for automatic file extension (suffix) is unchecked. When I export it, the filename gets a extension (suffix) '-01' behind it. When I export, check the box, and uncheck it, the file saves without the extension (suffix), like it should. So every time I have to check and uncheck the option before exporting. Very annoying. Never had this issue before.

    Newest updated installed 29.6.1 on Windows 10 Pro.

    Anyone else has the same issue?

  4. CEPHtmlEngine keeps macOS awake

    CEPHtmlEngine erroneously keeps macOS awake by setting PreventUserIdleSystemSleep

    See details below, CEPHtmlEngine is unnecessarily keeping macOS awake using the power management API and asserting PreventUserIdleSystemSleep, on this device it has been asserting and renewing its assertion for 170 hours.

    This presents a massive physical security risk to enterprise customers as it defeats IT controlled sleep/screensaver/walkaway preferences to lock the computer.

  5. HEX Franklin Variable Font is Not Visible when Editing

    I am on a Mac running Illustrator 29.4. I am trying to use the variable OTF version of HEX Franklin, and all Adobe apps do not render the letterforms. When I try to select the variable font in the dropdown, it just defaults back to Myriad or the default typeface.

    Other variable fonts work as intended, but specifically, this one is broken. Any possible fix?

    2. Check the "Embed allowed fonts for file preview" check box, save and close the file.
    3. Uninstall the specified fonts.
    4. Open the previous document in Illustrator.
    5. The character with the ALT specified will be displayed with the "notdef" glyph.

    Expected result
    The original appearance is displayed using the embedded font.

  7. Template Layers Still Visible on Export for PNG and JPG

    I am creating a logo package for a client and am attempting to export multiple logos / graphics with transparent backgrounds using the export panel. I've already confirmed multiple times that my PNG settings include transparency and that the View > Overprint Preview setting is unchecked. My background layer is set to non printing, however any PDF or PNG I export includes a visible background layer. I can completely hide this layer to avoid exporting it, but then I can't see my artwork correctly. The whole point of non printing layers is to see them when you are designing without…

  8. 画像トレースのパスが粗すぎる

    手書きの線画を画像トレースで取り込む時、パスが粗すぎて手書きのニュアンスが消えてしまいます。
    以前のバージョンまでは、細かくトレースされていました。
    イラスト制作が主な仕事なのですが、仕事に使用する上で致命的な欠点です。
    仕方がないので、まだ以前のバージョンを使用しています。
    早急に改善をお願いいたします。

  9. 中韓フォントの文字組みを変更してもアキが変わらない

    フォント「思源黑體 TW」の文字組みを「なし」や「行末約物半角」などに変更しても、アキ量が変化しない現象がありました。
    上記現象が発生したバージョンは下記の通りです。

    OS:Windows 10 Pro
    Illustrator CC:V 29.1、V 29.2、V 29.3.1(V 29.2.1、V 29.3は調べてません)
    なお、V 29.0、V 28.7.3 は当該現象は発生していません。

    問題発生時の手順:

    ・スクリプトを使いCSVデータを読み込んで文字情報を取得、文字をイラストに書き込む
    ・文字入力後、フォント「思源黑體 TW」へ変更
    上記どちらでも問題が発生します。

    想定していた結果:
    添付をご参照ください。
     V29.0文字組み「なし」.png
     V29.0
    文字組み「行末約物半角」.png

    実際の結果:
    添付をご参照ください。
     V29.1文字組み「行末約物半角」.png
     V29.1
    文字組み「なし」.png
    この2つの全角、半角のアキが同じ(変化がない)となっております。
    (どれを選んでも「なし」と同じ状態です)

    他のフォント(下記)で試してみましたが、アキ量の変化は確認できました。

    ・源ノ角ゴシック JP
    ・A-OTF UD新ゴ Pr6N L
    ・メイリオ
    ・游ゴシック

    Illustratorフォーラムにも投稿し他の方にもご検証いただいたところ、日本語以外(繁体字、簡体字、ハングル)のフォントで同様の現象が起きているようです。
    また、InDesign20.1(2025)でも同様の現象が起きているようです。

    バグであれば是非ともご対応いただけると幸いです。

  10. Artboard Borders / Guides / Grid Disappear when Scrolling/Panning

    When I scroll or pan with the scrollbars or the hand tool the black border of the artboards disappear. This is super annoying as I keep my canvas white, so when I'm moving around the canvas, I can't see where the artboards are until I release the hand tool.

  12. Moving a part of a blend with any Selection tool makes it move faster than expected

    In 29.7.1 (and Beta 29.9.0.6) when I move one object in a blend with any selection tool, inside or outside of isolation, it moves twice as much.
    This is similar to this problem with symbols — http://illustrator.uservoice.com/forums/601447/suggestions/50293512

  15. ドキュメントのグループの抜きを設定したドキュメントをPDFで書き出したものがオーバープリントプレビューの表示と異なる

    macOS13.6.7/iMac27inch(Intel)
    Illustrator ver.28.6

    再現手順
    1. いくつかの図形を重ねて合成モードを乗算に設定したうえでグループ化しグループの抜きのチェックボックスを外す。
    2. ドキュメントのグループの抜きを設定する。
    3. PDF X4で保存する。
    4. そのPDFをAcrobatで開く。
    5. Illustrator上でのオーバープリントプレビューの表示と異なる。

    Actual result
    PDFを書き出した状態とIllustrator上での表示が異なる。

    Expected Result
    PDFの表示とIllustrator上での表示が同じになる。

    Illustrator上でのグループの構造の違いがIllustrator上のレンダリング結果とPDF書き出し結果で相違が生じています。1でのグループの抜きのチェックを外したグループではIllustrator上ではグループ内ので抜き処理を行わず合成モードの処理を行います。これがPDFを書き出した際にグループの抜きと解釈され、全てがノックアウトされた状態でPDFが作成されます。どちらが正しいかという事は難しいのですが、グループに設定されたノックアウトを拒否する設定をPDF書き出し時にも有効にするほうが表現の幅が拡がるように思います。

    Step to reproduce
    1. Overlap some shapes, set each objects the blending mode to Multiply, group them, and uncheck the KnockoutGroup checkbox in the Opacity panel.
    2. Set the Page Knockout Group.
    3. save the document as PDF X4 format.
    4. Open the PDF in Acrobat.
    5. The overprint preview in Illustrator is different between PDF.

    Actual result
    The display in Illustrator is different from the exported PDF.

    Expected Result

  16. Missing fonts warning when no fonts are missing

    Every time I open any illustrator document, the missing fonts box shows up telling me all of the fonts are missing, but when I click replace fonts, they don't show as missing any more and there's no issue. This is a really annoying bug.

  17. Gray popup about Unpropping appears again and again

    A grey popup appears constantly whenever I am ungrouping things to tell me about ungrouping.
    Nothing in Preferences makes this go away and I see it repeatedly so closing it once doesn't work either. I really don't need training wheels and this should be one simple option to disable all large tooltips, blue popups and gray popups. There are already enough idiosyncrasies and distractions with Illustrator.

    3. The alterrnate glyphs are rendered with fallback to the default glyphs.

    Expected result
    The SVG filter will be applied with the alternate glyphs.

    Actual result
    The alternate glyphs are rendered with the glyphs changed to the default glyphs.

  19. Threaded text area box disappears after saving

    MacOS Ventura 13.7
    Illustrator 28.6 and newer

    When I convert a document to curves, save a copy, and then press Undo so I can have the text boxes editable again. As soon as I press Save after doing this, the second text frame in a thumbnail in Finder vanishes, while still existing in the document.

  20. 線を細く設定した際の表示バグ

    線の太さを0.001pxなどに設定した場合、設定は出来ているのに実際の線の表示位置と、選択できる線実体の位置にズレが生じます。
