Welche Einstellungen müssen gemacht werden, damit ein Logo im ai. Format nicht pixelig wird im Ausdruck? Momentan habe ich das problem, dass beim Plottausdruck das Logo sehr pixelig wird und die Farbe anders gedruckt wird.

Lydia,

 

A logo that is (also) used for print ought to be (originally) created in CMYK Color Mode, not RGB, because othewrwise the final colours will be disappointing. RGB has a wider gamut (span of colours), and especially bright and vibrant colours are lost when turned into CMYK. In this way you get the most consistent colours across all different uses, both print and screen; and the conversion into the wider RGB gamut is far more satisfactory than conversion into the narrower CMYK with significant loss of colours.

 

And it ought to be printed directly from the vector artwork, not from a raster format such as PNG/JPEG (JPG). Raster formats are made of pixels (small squares) at a sudden size determined by the resolution. When scaling up, or with inadequate resolution, the pixels can be seen.

 

Vector artwork remains smooth when scaled up, so you get the best possible resolution that the printer can produce.

 

It is best to print on a printer using a PostScript (emulating) driver to remain in CMYK all the way and get the best possible quality including resolution.

 

If you print on a non PostScript printer, you get better results if you save a copy of the logo as PDF (make sure to avoid wrecking the artwork by saving it as PDF so you use the original AI version) and print from Acrobat.

 

Further, if you print on a small office/home printer, it will work with RGB and convert the Cyan/Magenta/Yellow (and blacK) to Red/Green/Blue in its own way, thereby making 2 colour mode conversions, first CMYK > RGB then RGB > CMYK, with significant loss of quality; in that case it will be better to convert the artwork to RGB in AI in a controlled manner.

 

 

And in any case colour management is also important.

Als was speicherst Du die Datei?

Und von welchem Programm druckst Du sie?

Was für ein Drucker ist das?

Wie sieht das Ganze aus? EIn Foto wäre gut. Vielleicht ist es gar nicht pixelig, sondern ein Halbtonraster.

Das sind einmal die Logos in den jeweiligen Dateiformaten und einmal ein Bild vom Ausdruck. Drucker ist ein Plotter. Logo wird aber auch auf Monitor manchmal pixelig angezeigt.

Lydia,

 

Whatever else may be said, the PNG seems to be at an inadequate size/resolution.

 

Apart from that, you may some of the following useful in connexion with raster formats; see also remark at the end about SVG which can be seen as a vector equivalent of a PNG for some screen uses.

 

 

The following may sound unforgivably outdated and boring, sorry.


If you wish to have PNGs (PNG24 (also (little) known as PNG32, it holds 24 bit colour and 8 bit Alpha channel (transparency)), of course) look crisp and clean, at least when it is (also) to be used at moderate screen resolutions, it is important to have the images in the exact desired final pixel x pixel size, or at sizes that are powers of 2 times as large (2x, 4x, 8x, and so on, the larger values can improve the appearance on high resolution screens and still ensure best possible appearance at low resolution screens); forget about image resolution which may actually lead to wrong sizes and hence blurriness, or work at 72PPI or powers of 2 times as large (144PPI, 266PPI, 576PPI, and so on).


It is easiest and safest to work at the desired size when creating the artwork.


It is important to remember that a raster image represents the whole appearance, including strokes, so to make sure you get it right you can click Show Preview Bounds in the General Preferences (and untick it afterwards).


A very common unsuitable way is to Export to PNG (remember to use PNG24 and use Transparency for artwork to be in front of different backgrounds) with a medium or high resolution, such as 300PPI.


And a common misunderstanding: (almost) 11 out of 10 times, a statement like "I created the document at 300 PPI" means that the value is chosen in Effect>Document Raster Effects Settings; however that only means that the (current) resolution of any raster effects applied to the vector artwork, such as (any kind of) Blur, is set to that value (and only unless/until the value is changed to something else); when zooming in, this resolution can be seen in contrast to and on the background of the vector artwork. So this setting has nothing whatsoever to do with the actual resolution of a raster image created from the (vector) artwork (but it ought to (at least) match it).


For clean and crisp artwork avoid JPEG.


It is also important to have the artwork and also the Artboard(s) placed fully within integer/whole pixel X and Y values in the Workspace, which means that the X and Y values at the corners must be integer; this can be ensured by using one of the corner Reference Points in the Transform palette, and then checking that all the values X, Y, W, and H, are integer (the centre Reference Point can only be used if both W and H are even numbers).


If you have issues with the Artboard(s), make sure the rulers are Global Rulers (RightClick), if not change from Artboard to Global Rulers; and to align your artboards, click the Rearrange All Artboards button in the Artboards panel. First posted by Ton here,
https://community.adobe.com/t5/illustrator-discussions/why-is-illustrator-not-exporting-artboard-siz...


Otherwise the resulting image will become a bit wider/taller and the extension(s) will be empty and therefore be (partially) transparent/white.


Therefore, a safe way is to create the artwork at the final pixel x pixel size and use a corresponding Artboard, then use the Legacity Save for Web (where you can look in the Image Size window for size confirmation and possibly multiply by 2, 4, 8, whatever), or use Export at 72PPI (or 144/288/576/whatever PPI), or use Export for Screens (in either way). In either case, use the relevant optimization (available with both ways); it is also convenient to have 72PPI (or 144/288/576/whatever PPI) in the Effect>Document Raster Effect Settings.


If you have pure vector artwork, you can relax a bit and have the artwork/Artboard at any size (the Artboard must have the same proportions as the final image), then use the Legacity Save for Web and set either Width or Height in the Image Size and Apply (make sure the other value is also correct).


The Legacy Save for Web may be an old carthorse, but it knows its way home, even if the driver is drunk and sleeping it off in the hay in the back.

 

Or you can switch to SVG, if applicable.

Was für ein Plotter ist das? Ein Stiftplotter? Oder ein großer Tintenstrahlplotter?

Und welche Software kommt für den Ausdruck zum Einsatz? Illustrator? Oder irgendwas anderes?

Es ist ein großer Tintenstrahldrucker. Das Logo soll im Schriftfeld einer Zeichnung (Autocad) eingefügt werden und gedruckt werden. Das Problem ist aber generell, wenn ich es skaliere, dass es dann pixelig wird.

Neben dem Auflösungsproblem - falls es eine Pixelgrafik ist - kann dann noch die Fähigkeit des Druckers eine Rolle spielen.

Bei Pixelgrafik muss die Auflösung ausreichend sein (dazu hat Jacob etwas geschrieben). Bei Vektorgrafik müssen der Drucker bzw sein Treiber bzw die für den Druck verwendete Software in der Lage sein,  die Grafik aufzubereiten.
