What do you like best?
It's simple and easy. I can pull forms from the internet, email, my desktop, etc and fill them in for a professional look.
What do you dislike?
The printing process could be laid out a little more simply. It works well; but a little 'clumsy' vs smooth like printing in microsoft products.
Recommendations to others considering the product:
It an efficient product that makes all documents/applications/etc look professional.
What problems are you solving with the product? What benefits have you realized?
Completion of all business forms look professional. We've eliminated handwritten credit applications. It's efficient to create and especially for credit applications, we save the prior information there so easy to update.

Just started using it today
Just started using it today. I'm afraid it will only let me save 5 documents to my computer because I got a pop-up about that

Works well with scanned pdfs to
You can wite-out on the page when you need to change some data. You can highlight, it has most features like other pdf programs.
The time it takes to upload takes longer than with adobe acrobat.

I converted my word file to PDF file
I converted my word file to PDF file. Excellent!
The program is designed very well.
Thank you very much for this free gift.

I reviewed this software for my company…
I reviewed this software for my company (we historically use another product) for function and usability. It is significantly more user friendly than the others that do similar functions. What makes this a good decision is the cost and the support. It costs a third of the software we currently use and when I experienced a problem (on the weekend) I had (professional and personal) support online in less than a minute. Very satisfied.

What do you dislike?

What problems are you solving with the product? What benefits have you realized?
Edit CV, payroll, invoices and other documents easily

Which light is suitable for getting maximum resolution?
Since the limit of resolving power of a microscope is fixed by the structure of light, the shortest wavelength of visible light will give the maximum resolution. Among yellow, green, red and blue light color. Blue (500 nm) have the shortest wavelength so, it will give the best resolution.
Which light gives the best resolution in a microscope?
The greatest resolving power in optical microscopy is realized with near-ultraviolet light, the shortest effective imaging wavelength. Near-ultraviolet light is followed by blue, then green, and finally red light in the ability to resolve specimen detail.
Which wavelength of light will give the best resolution in a light microscope?
Near-ultraviolet light has the shortest usable wavelength and offers the greatest resolution. Following near-ultraviolet in descending order of wavelength are red, orange, yellow, green, blue and violet. The range in nanometers of the wavelength of the visible light is from 380 nm to 750 nm.
What is the resolution of a light microscope?
The maximum magnification of light microscopes is usually ×1500, and their maximum resolution is 200 nm, due to the wavelength of light. An advantage of the light microscope is that it can be used to view a variety of samples, including whole living organisms or sections of larger plants and animals.
How can you increase the resolution of a light microscope?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
What can be done to improve the maximum resolution of a light microscope?
The resolution of a specimen viewed through a microscope can be increased by changing the objective lens. The objective lenses are the lenses that protrude downward over the specimen. Grasp the nose piece. The nose piece is the platform on the microscope to which the three or four objective lenses are attached.
What is the limit of resolution of a light microscope?
The resolution of the light microscope cannot be smaller than the half of the wavelength of the visible light, which is 0.4-0.7 µm. When we can see green light (0.5 Am), the objects which are, at most, about 0.2 Am. Below this point, light microscope is not useful, as wavelength smaller than 400 nm is needed.
How do you improve eye resolution?
In order to increase the resolution (d=/2 NA), the specimen must be viewed using either shorter wavelength () light or through an imaging medium with a relatively high refractive index or with optical components which have a high NA (or, indeed, a combination of all of these factors).
