How to check resolution of a pdf with Acrobat Pro

Many people ask how to check resolution of a pdf with Acrobat Pro however the short answer is you can’t. This is because a PDF does not have one overall resolution. The elements within the PDF are what you need to check the resolution of. These may all have the same resolution or they may differ and it’s really simple to check resolution with Acrobat Pro and below I will explain.

STEP 1
Open the PDF you intend to check in Acrobat Pro

A common question I come across is ‘can you make an image black & white (B&W) in InDesign without using Photoshop or another application or software’, the simple answer is yes you can.

The slightly longer answer is that this process will allow you to make image appear black & white, but it will not convert your image to greyscale, that can still only be done with Photoshop or similar. So just bear in mind that this process will show you how to make your image black & white in InDesign but the images will still print in full colour as they have not been truly converted to greyscale.

Below I have written a step by step guide hopefully covering all areas to tell you how it is done. If you prefer a video over written instructions well you are in luck as I’ve made one of those too.

How to make an image black & white (B&W) in InDesign without Photoshop

STEP 1
Open the document with the image you wish to change in Indesign. To do this go to ‘File’ in the menu at the top of the page and select open.

Then navigate to the document you intend to open and click ‘Open’ in the bottom right hand corner of the pop-up box.

STEP 2
Click on the ‘Swatches’ panel located (by default) in the menu on the right hand side.

If you are unable to find the swatches panel here you can open it by going to ‘Window’ in the menu at the top of the page, select ‘Colour’ and then click on ‘Swatches’. This will open the panel.

STEP 3
In the Swatches panel click on ‘Black’.

Ensure you have the ‘Fill’ colour filled black and not the stroke.

STEP 4
Now draw a box over the image you want to convert to black and white (B&W). To do this select the ‘Rectangle tool’ from your tool bar.

Click on a corner of the image and drag over the entire image. I would recommend zooming in and checking that the box lines up exactly with the edge of you image.

STEP 5
You should now have a solid black box covering your image.

With the box selected go to the ‘Effects’ panel which is usually located in the right hand side menu.

If you are unable to find the effects panel here you can open it by going to ‘Window’ in the menu at the top of the page and click on ‘Effects’. This will open the panel.

STEP 6
Click the drop down menu in the top left hand corner of the effects panel.

STEP 7
Select ‘Colour’ from the drop down list.

Your image will now appear black & white (B&W).
