Hola comunidad, he hecho esta publicación porque tengo un problema al exportar un logo desde Illustrator.
Lo que pasa es que al estar en las opciones de exportación y calidad de la imagen yo lo pongo a 300dpi la máxima calidad y con fondo transparente con la optimización para ilustraciones, pero al ver el archivo exportado si se ve an buena calidad pero todas las formas se ven como pixeladas.
Un ejemplo es una línea en diagonal que se supone tendría que ser una sola y bien delineada, se ve como si estuviera compuesta por otras mas lineas horizontales.
No se si exista una solución a este problema. Agradezco sus respuestas 🙂
He dejado una captura de la imagen, esta a 300dpi optimizado para illustraciones y formato png con fondo transparente. En la otra encierro las áreas que no se ven bien trazadas, pero en Illustrator si se ven bien no entiendo porque al exportarlo se ve así.
Nota: La imagen original me exportó a 9000 x 6433 pixeles con un peso de 805 KB, no se si será porque es muy grande el tamaño, pero espero sus respuestas pues estoy aprendiendo en esto 😕

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Illustrator forum so that proper help can be offered.
Thanks, i didn't know how to use this.
You are welcome, Daniel.
If I may ask: SVG or some other way?

The following may sound unforgivably outdated and boring, sorry.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 ensure best possible appearance at low resolution screens); forget about 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 repesents 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 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).
Otherwise the resulting image will become a bit wider/taller and the extension(s) will be empty and therefore be (partially) transparent/white.
Therefore, the safest 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.
