White Image on White Background Shows up on Page

[SimpleSi]

One of my schools got a new colour laser in their office and strange things happen with logos with white backgrounds in Word.

 

If you insert a BMP version of the logo into a document, the white background of the image is visible, very very faintly on the printed output.

 

If you adjust the image properties within Word (brightness /contrast) you can make the background invisible (but you have to do this every time you insert a logo into a document)

 

If I convert the image to jpeg and insert it then the background is invisible when it prints out.

 

Any ideas? - has this happened to you?

PS The backgrounds really really are totally white col=#000000.

Jpegs are compressed. Your image editor would of uniformly set the background colour to make the compression work better. Hence white really is white as far the Jpeg goes.

 

Bitmaps don't. Therefore any shadowing or discolouration (presumably this is a scanned image) will be preserved and faithfully reproduced by the laser printer.

Click the transparent button on the image toolbar and click in the white area.

gifs and png (i think) will save transparancy information. Don't know if word takes any notice of it though.

The white in the image is whiter than white (honest)

 

The problem only became noticable when the colour laser was installed - it wasn't noticeable on the previous inkjet.

 

Its as if Word thinks - ooh a bitmap image - instead of ignoring the white background I'll make sure I tell the printer to just make it slighty ever so slightly off-white. :?

 

Do any of you have some nice colour lasers - if so just give it a go with a monchrome (black and white) bitmap image inserted into Word and see if you can tell the difference between Daz and another leading powder

@SimpleSi: Perhaps the printer's colour calibration settings are wrong.

 

Besides... why the hell would you want to insert a bitmap into Word? Have you suddenly found a few gigs of storage that needs using up?

[SimpleSi]

If the logo is small then jpeg artifacts can be slightly annoying.

 

AFAISI the printer only prints what its told and it must be being told something different for a bitmap image v a jpeg

 

I was just trying to see if anyone else had noticed this effect at all cause its a bit weird :?

@SimpleSi: You don't mention what the printer is. Maybe someone else has noticed a similar problem with that model.

 

You may need to dig in the printer settings for the calibration settings... there's usually something in there though.

Too much Daz??

[SimpleSi]

"Too much Daz"

 

Yep - I'll stick to square deal Surf
