Bitmap Images in Ultiboard Copper Layer

[ekent]

I am trying to use a bitmap image in the top copper layer of a PCB and the image looks good on screen, but when I view my gerber output in Viewplot there are hundreds to thousands of horizontal lines running through the image causing it to fail the manufacturers DFM check.  Is this a problem in the way Ultiboard is handling the image or in the way Paint saved the image and does anyone know what I can do to fix it so I can get these boards off?

Hi ekent,

Can you please post the file and the image and we will take a look to see what is causing the issue.

Attached are the Ultiboard file, BMP image, and the exported Gerber layer that shows the horizontal lines under high zoom levels.

Hi Ekent,

I looked into your file and it seems that you will have to either import this picture as a DXF or you will have to draw it in Ultiboard and save it as a part. I cant find a way to make it work using a simple BMP picture. I tried to draw the logo in Ultiboard. I have attached the file which has that part included. You can save it to your database and edit it as needed to make it look more accurate. I have informed R&D about the issue as well.

I apologize for any incovenience and hope this helps.

Hi,

Just an update on this issue.

Bitmaps that you can import in Ultiboard have to be saved as "monochrome bitmaps"... in Paint, just change the file type to monochrome bitmaps before you save. If you have a colour bitmap, it will show up as a box in 3D view and gerber export. With the monochrome image only 3D view will show a box... but gerber should export OK.

You can use Paint to convert any image to monochrome and to invert the colour if needed. The background must be black and the pixels you want to show must be white. As always, a DXF version of a logo is very much preferred instead.
