  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. Em dash incorrectly rotates upright in vertical text layout

    Illustrator 2025 (29.8.1) (29.8.2) Japanese

    Em dashes are Latin characters, so in vertical text layout they should be rotated sideways like other alphanumeric characters.
    However, in v29.8.2, Em dashes are rotated upright like Japanese characters. This is clearly a bug.


    EMダッシュが縦組みで正立回転する

    EMダッシュは欧文の文字なので、縦組みでは他の英数字を同じく横倒しになります。
    しかし、v29.8.2では、和文の文字のように正立回転してしまいます。これは明らかにバグです。

  3. Swatches disappear in Swatches panel when switching between documents

    I've got two documents open. An RGB one, and a CMYK one. When I CMD+TAB between the two, all the current swatches disappear. I have to click on a different 'view swatches' button to make them appear. This happens EVERY TIME. I just updated to the latest version of Illustrator thinking it would fix it, but it doesn't.

  4. Scroll wheel is very slow and unresponsive in Adobe Illustrator 30.0

    Since updating to 30.0 today, the UI seems very slow, particularly when using the scroll wheel to navigate the canvas.

  5. Font styles applied to portions of text 'slide' / shift positions when area type overflows

    Illustrator 29.7.1 on Mac Ventura 13.5.2 (22G91)

    I dont' know whether it's related to this current issue, but now I have parts of my text that change appearance when I'm trying to change the Font weight of another part, or when I try to type more text.

    The workaround I have found it copy-pasting the text into a new Textbox. But still, this needs to be fixed.

  6. Illustrator 2026 adds a previously selected object to a newly selected one when moving the new one

    macOS Sequoia 15.6
    Illustrator 30.0

    Just selecting and moving basic objects is not functioning correctly. Was this tested at all? I've restarted the app, I've restarted my machine. It's just buggy AF. I've had to revert to previous version just to get a simple chart done.

  7. Images embedded disappear after reopening the file 2025

    This problem has been occurring for a few weeks: when I reopen a file containing embedded images, they disappear, turn white, or turn the original image color.

    In 15 years of using ILLUSTRATOR, this has never happened, and it's truly annoying. Some files contain more than 50 images, and if a small one disappears, it's unmanageable.

    The strange thing is that it doesn't happen with all files; it's random.

    I'm working with Illustrator 30.0, but the same thing happened with 29.8.3.

    Looking through various forums, you may already be aware of this problem.

    Please fix it, as we pay a…

  8. 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. Pattern Scale Not Working

    My pattern scale has stopped working recently for user created patterns (it works ok on the default patterns). Previously I could create a pattern but dragging into the swatch menu, and then when I dragged the corners, the scale of the pattern would adjust along with the size of my shape. Now it does not.

    I have checked that "Transform Both (object and pattern)" is selected from the Transform Panel dropdown, along with Settings > General > Transform Pattern Tiles is also checked on.

    This has been going on since late July 2025 - I've tried every troubleshooting method I…

  11. Pasting an object with perceptual gradient applied expands it and converts into an image

    1. Create a rectangle and fill it with a gradient (liner/radial)
    2. In the gradient panel, change the method from Classic to Perceptual
    3. Copy the object
    4. Paste the object

    Check the Appearance panel — it’d show the object is now an image, with the original perceptual fill tucked under the pixels!
    And if the object had a stroke, it becomes a group with a stroke in it separated.

  12. "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…

  13. Curved paths not honouring guide styles / Guides are not dotted

    When converting artwork to guides, anything that has a curved path does not show the guide style set up in preferences. In my case I have guides set up as a dashed line with a light grey colour. What I'm seeing is a solid black line. Happens in AI 29.6.1 and the beta 29.7 88. Sample shows two shapes converted to guides but the ellipse remains as a solid black line. Using MacOS 14.7.6.

  15. 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"…

  16. Keyboard shortcuts for text formatting (kerning, tracking, leading, font size) no longer work in Illustrator 29.7.1

    This feature just stopped working. Please fix.

    These also don't work:

    Increase or decrease leading: Option + Up or Down Arrow (horizontal text) or Right or Left Arrow (vertical text)

    Increase or decrease kerning and tracking: Option + Right or Left Arrow (horizontal text) or Up or Down Arrow (vertical text)

  17. Scaling down a placed image makes it unmovable

    After placing a PNG and scaling it down to fit my artwork, I was no longer able to move the PNG into place. I could only select it in the Layers panel or by clicking and dragging over it. There does seem to be a threshold before this happens — if I only scale it down a small amount, it seems to behave as normal, but if I go beyond 50%, it becomes unstable. Of course, the workaround is to scale the PNG closer to the size needed, but this behavior seems to be new. I am pretty sure I…

  18. Creating and/or Entering Opacity Mask doesn’t work from Properties / Control panels

    When clicking on the Opacity popu-up panel (in Control or Properties) and then clicking on the mask thumbnail to activate that mode, the thumbnail highlights but as soon as I attempt to edit the contents of the mask, it shows that the mode is not activated. Only if I select the 'Clip' checkbox in the Opacity panel will it allow me to edit the mask. But then clicking the 'Object' thumbnail in the Opacity panel, similarly does not exit mask-editing mode. I have to uncheck the 'Clip' checkbox to get back to normal mode. Previously, simply clicking on each thumbnail…

  19. 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.

  20. Can't see any Artboards

    Every project I access opens, but I can't see any artboards. I have tried downgrading and uninstalling+reinstalling, to no effect.

    Would be grateful for any input on my situation.
