Hi
In a case like this, an image file is useless.
We need to duplicate the problem so please send a small sample file with instructions on what you’re doing so we can repeat the problem here.
Thanks
file - print
page size- 44" x 30"
scale 1/4" = 1’
raster (vector has the same results)
media and quality - best
export as PDF
send email as attachment
when the file is viewed in the internet viewer the file is missing information visually (prints fine and can be viewed fine in adobe acrobat) but the clients receiving the email hardly know how to use computers.
It appears it’s a combination of the limitations of the less powerful viewers, and the large sheet size you’re using.
It looks like the skinny lines (0.25mm at 44x30) are sampling down too small. If you print to a Tabloid size sheet size instead, they look a lot better. I assume this is because the lines are wider.
Since Rhino is making a valid PDF file, I don’t think there’s anything to be done on this end.
The receiving party will have to “up their game”, or you’ll have to send them a dumbed down PDF they can deal with.
