How to Export tiff from AutoCAD

[Amin]

Could someone please tell me how to prepare a 600 dpi tiff image from AutoCAD with the width of 10 cm at least?

 

The tiff file resolution (600 dpi) and the image width (minimum of 10 cm) is critical for me since I have been requested to submit my images in this format.

 

Thanks!

Don't you have to divide pixels by dpi in order to arrive at page size? In my test of the TIFOUT command I did not see any option for changing the resolution.

 

How about using something like TIFF Image Printer? Click on link.

Remark is correct you need to make a custom plot sheet size so that it reflects your pixel desired DPI and title block size. Just use the default to TIff plot driver. We have done this for a few years now and reproduce the dwgs perfectly but only in mono.

 

Anyway here is how, our title block is 801x556mm we need to work in DPI so this is 6307x4377 at 200 dpi. 200 was chosen as the original image is a A1 sheet normal reproduction is A3 1/2 size more than adequate. You just use the window option and pick the same two corner points that you have used to calculate your plot area. I would only go to 300 dpi you will only swell the TIff size but with no real image quality improvement. The second thing we found is that we use a different CTB file for the plots we had to reduce all line thickness by at least 1/2 as the line work was actually to dark when reprinted.

 

The maths 801/25.4*200=6307

 

Again you can use publish or in our case a plot all layouts to tiff lisp makes life easier. If wanted as one there are Tiff combiner programs.

600 dpi and 10 cm (4"), so you need at least 2400 pixels of width.

Go to File->Plotter Manager

Select Add-a-plotter-wizard

Select Raster File Formats/TIFF as Plotter Model/Manufacturers

Keep clicking [Next] until you get [Edit Plotter Configuration] andselect it

Go to Custom Paper Sizes and click [Add]

Set up required resolution

Use the TIF plotter to create your TIFs

 

see attached file test_2400_2400.zip for an example of a TIF image produced from an AutoCAD drawing

Thanks Pefi you can also get to the set up via the properties option in the plot dialouge.

 

Amin you need to work out your sheet size 10cm min will give different resoloution answers if you use it and pick a 20cm sq this will halve the DPI. I have multiple tiff sheet sizes setup.
